  • Some club members will now enter a changing booth and change their clothing before engaging in a club activity. This was only possible because of help from Saracen!
  • If the player speaks to a Club Leader who is in their clubroom, club-specific dialogue options will appear.
  • The player can ask a Club Leader for information about their club, ask to join the club, ask to quit the club, or ask to participate in club activities.
  • If the player asks to participate in club activities between 5:00 and 5:30, they will be shown a scene that features Yandere-chan participating in the club’s activity, and the day will end.
  • If the player reduces the number of students in a club to less than 5, that club will disband. The club members' daily schedules will change, their appearances may change, and the doors to the clubroom will be locked.
  • If a club member witnesses Yandere-chan commit murder, but Yandere-chan is not arrested for murder, that student will warn the club's leader about Yandere-chan, and Yandere-chan will be kicked out of that club, or disallowed from joining that job in the future.
  • If the player murders the leader of a club, that club will disband.
  • If the player quits a club, they won’t be allowed to re-join.
  • If the player takes an action that would result in a club disbanding (such as reducing the number of students to less than 5, getting kicked out of the club when the club only had 4 other members besides the player, or murdering the club leader) then the player will be shown a message at the end of the day in which Yandere-chan is informed that she has been kicked out of the club.
1/2/2016
  • Instead of having Yandere-chan drop her weapon when the day ended, Yandere-chan will bring her weapon home with her which will count as disposing the weapon.

  • Removed images of unfinished future content that people weren’t supposed to find out about yet.
  • Did a better job of hiding the Student Council President.
1/3/2016
  • It is no longer possible to put on new clothing in the locker room if Yandere-chan is wearing a club uniform. (It may be possible in the final game, but not for now.)
  • If the protagonist becomes bloody while wearing a club uniform, she is allowed to take off the bloody clothing in the locker room. The bloody club uniform will appear on the ground as a pickup. It will not be possible to change back into the main character's club's uniform for the rest of the day.

  • Added Bad Time Mode.
2/1/2016
  • There are now 7 Personality types, or “Personas” in total.
  • The 3 new ones are Coward, Evil, and Social Butterfly.
  • (Female) Students will now react when the player aims a camera at them. Their reaction depends on their personality.
  • For now, all male students will have the Loner personality or Teacher’s Pet personality, and will not react to the camera. I can’t give them other personalities or reactions because, at this point in time, I don’t have an animation rig for male characters, and I can’t transfer female animations to male skeletons.
  • If the player joins the Photography Club, students will not react to the camera, and will allow the player to Photograph them without any problems.
  • Added a humorous “WARNING” message to the beginning of the game. I might remove it, if people complain that it gives the game the wrong vibe.
  • Added a bunch of “Fake” students who exist so that the player can join clubs that don’t have official club leaders yet.
  • An accessory will now appear on Yandere-chan’s body when she joins certain clubs (Cooking, Occult, Martial Arts, Photography).
  • Attempted to improve the framerate of the game by making optimizations to certain scripts.
  • Added hair physics to some long hairstyles that were lacking physics.
  • Gave each teacher in the game a unique appearance.
  • Added a greenhouse to the gardening club zone.
  • Added 6 new hairstyles for Yandere-chan.
  • Added 1 new hairstyle for Senpai-kun.
  • Ever since the first week of the game’s development, Yandere-chan’s eyes would shrink when she lost her sanity. Previously, her eyes would shrink into very small dots. This reflects an “angry” character, not a “hollow” character, so I have changed the minimum size of her eyes. Her eyes can still shrink, but not as much as before. Her eyes are meant to say “I am empty and dead inside”, and not “I am violent and crazy.”
  • Previously, Yandere-chan’s eyes would become blank and lifeless when “Yandere Vision” was activated. Now, they become blank when she loses sanity.
  • Now, when Yandere Vision is activated, Yandere-chan’s eyes become red.
  • A shadow now gradually falls over Yandere-chan’s face as she loses sanity.
2/2/2016
  • It is no longer possible to tell a student to "Go Away" if they are currently walking from one place to another. It is now only possible to tell a student to "Go Away" if they have actually reached some destination that they intend to occupy for some time.
  • Previously, telling multiple students to "Go Away" would cause them to all travel to the exact same spot and attempt to occupy one position in space. Now, telling multiple students to "Go Away" causes them all to go to different spots.
  • Telling a student to "Go Away" will no longer make them spend hours standing alone somewhere. They will now only “Go Away” for a maximum of 60 seconds.
  • Students are no longer willing to perform favors for Yandere-chan if their next class begins in less than 30 minutes.
2/8/2016

  • All body parts (head, torso, arms, legs) can be picked up, carried, dropped, and incinerated.
  • NPCs and police do not react to body parts yet.
  • As of now, dismemberment only works on females.
  • As of now, the body parts that appear after dismembering an NPC will always be clad in the default uniform.
  • It is now impossible to struggle against an NPC if the protagonist is holding a weapon that is too large to conceal, such as the katana or the circular saw. If a weapon is too large to conceal, then it's too unwieldy to use in close quarters and would only make Yandere-chan more vulnerable during a struggle.
  • At the request of an important person, all Undertale audio assets are now removed from the game, and the appearance of the "Gaster Blasters" has now been altered so that they are completely unique.
  • It is now possible to pick up a corpse and carry it while walking or running, if the player has leveled up their Physical Education stat at least one time.
  • Implemented a real "dump corpse into incinerator" animation, rather than re-purposing a "throw" animation in order to place a corpse into the incinerator.

  • Added a work-in-progress exterior to the school gymnasium.
  • Renamed Shi Ta to Shima Shita.
  • Added two new hairstyles for Senpai.
2/17/2016
  • Mai Waifu now has rainbow-colored eyes. In other words, her eyes now gradually change their color, cycling through every color of the rainbow, every moment of the day.
  • Students now have a spoken reaction to witnessing the player carrying around a circular saw.
2/21/2016
  • Attempted to implement support for all aspect ratios, not just the 16:9 aspect ratio that I've been using up until now. Warning: Any aspect ratio other than 16:9 will be buggy during Yandere Vision.

  • Gave the titans in Titan Mode a new texture.
  • Removed several copyrighted tracks and replaced them with original tracks.

  • Removed the D debug command.
  • Replaced the sound effect when the player travels to the void.

  • Added a new background track to the game (that means adding 9 versions, one for each combination of atmosphere and sanity). When the school day begins, the player has a random chance of hearing the old track or the new track.
  • Added voiced lines for the Pain Demon.
  • Moved the incinerator to a new location.
  • Placed delinquents outside of the garbage disposal zone.
  • Replaced the guitar case with the cello case.

  • Most club benefits were added and became functional.
  • Club accessories were added.
  • Replaced two copyrighted tracks with music from The Kira Justice.
  • Modified appearance of the female delinquents.

  • Added fire extinguishers to the school.
  • Removed the "Warning" scene.
3/31/2016
  • As of now, when multiple button prompts are visible onscreen, the game will highlight the one that is closest to the center of the screen, rather than the one that Yandere-chan is standing closest to. (This fixes the “Can’t pick up objects dropped near incinerator” bug.)
  • From now on, if a student witnesses a corpse while they are running to the locker room to change their clothing, they will switch their personality to “Loner” and run out of the school, instead of following their normal corpse-reaction routine.
  • Previously, when a student was following you, they would run when they were more than 5 meters away from you, and walk if they were less than 5 meters away from you. Now, students will run until they are 2 meters away from you.
  • Nearby pickups now have a little icon floating above them, instead of having a button prompt and name above them. The button prompt and the name of the object won’t actually appear until the player gets close enough.
  • Added textures to the castle area in Yanvania. Yes, that’s right, textures! Previously, the whole thing had no textures whatsoever! Everything was using solid colors until today! Check out Yanvania again!
  • When the player looks up a character’s information in the Student Info menu, “Club” will now change to “Occupation” when displaying the information of an adult.
  • Now, if the player kidnaps the week’s current rival, reduces her sanity to 0%, brings her to school, and hands her a weapon, she will commit suicide.
  • Updated Yandere-chan’s character model to use her trademark black stockings at the character customization screen.

  • Added a new hairstyle for Senpai.

  • Replaced the copyrighted music from the Cyborg Ninja easter egg with an original track by Damprog Music.
  • It is now possible to customize Senpai with facial hair.

  • Added Kokona’s task to the Task menu.
6/6/2016

  • If the player mashes the Confirm button (“E” on keyboard, “A” on controller) after Yandere-chan trips, the “stand up” animation will speed up.
  • At this point in time, Kokona is the only character who will react to being splashed with liquid from a bucket.

  • Mind-broken slaves will now spawn to the right of the school gate, behind some bushes, to provide an explanation as to why the gym teacher and other students don’t notice them.

  • Improved the mind-broken slave’s suicide animation.

  • The idea with Social Butterflies is that they would run and hide in heavily-populated areas.

To combat this problem, Social Butterflies now run to a collective hiding spot and huddle together, rather than “hide” in plain view of the killer.
  • Researched and successfully implemented a method for modifying textures while the game is running. (You can currently only see one example of this in the game right now: Midori’s stockings and panties are now green.) This opens up tons of customization potential in the future!

  • If your Physical stat is above 0, it is now possible to have a struggle against a teacher, and kill that teacher.
  • Now, when a teacher is killed, they will be replaced the next day by a randomly-generated teacher.
  • Added new struggle animations (for students and teachers).

  • Items will now disappear out of a student’s hands when they witness murder.

  • Updated Yandere-chan’s “about to be apprehended” animation.
8/12/2017
  • Time will now pass at 50% normal speed during Lunchtime. This is because a lot of story events will occur at Lunchtime, and the game’s clock was ticking by way too fast for all of those events to occur within that phase of the day.
  • Improved the animations that Yandere-chan and students use when students are gathering around Yandere-chan and preparing to perform a group takedown on her.

9/2/2017
  • Because everyone unanimously agrees that LoveSick’s Senpai creation screen is objectively superior to the previous Senpai creation screen, the default Senpai creation screen is now a pink version of the LoveSick Senpai creation screen.
  • Adjusted the settings for the “Rim Light Test” that is accessed by pressing the “R” key at the Settings menu. If you weren’t satisfied with how it looked before, try it again!
  • From now on, if the game is desaturated (because of low school atmosphere or LoveSick mode) the colors will temporarily return when Yandere-chan walks near Senpai.
  • There is no more “Yandere Simulator or LoveSick?” screen. Now, the only way to activate LoveSick Mode is to press “L” at the title screen.

  • The player will now hear a voice clip from Info-chan when setting a bug.
9/5/2017

In the latest build, the player will now use a different button to set a bucket of water above a doorway.
  • The “Gentle Eyes for Mai Waifu” feature it’s now properly disabled in this new build.
  • Senpai will now consider it to be suspicious when Yandere-chan is aiming a camera at his face, and will react the same way he does when Yandere-chan is acting weird in his general vicinity.

  • It’s now possible to toggle “Rim Light Mode” on and off by pressing the “R” button in the Settings menu.

  • Coming to school at 8:00 will now cause students to stand where they would logically be standing at 8:00, rather than teleport directly to the destination they’re supposed to have at 8:00 (their classrooms).

  • The “Change Persona” mirror is functioning properly again (although it’s still only used for testing purposes, and not attached to a proper-implemented gameplay mechanic yet).
  • If the player is playing a “Clean All Blood” mission in Mission Mode, cleans all blood, and then spills NEW blood, the player will now be required to clean up the new blood.
  • Text during the end-of-day police investigation sequence will now list dead characters with proper grammar (with commas, instead of repeating the word “and”).
  • Yandere-chan’s hair and accessories are now disabled when aiming her camera, so that large hair / accessories don’t block first-person view anymore.
  • Midori now wears green socks instead of green stockings, because there was already someone at school wearing green stockings.

  • Male students will now close their eyes when clapping erasers at Cleaning Time.
  • Added profiles for the Counselor, Headmaster, and Info-chan.
12/18/2017
  • To prevent an exploit that would allow the player to seperate a student from other students by talking to that student repeatedly, a student will now become annoyed with Yandere-chan and refuse to speak to Yandere-chan if the player lets the student’s patience run out twice during a conversation, or ends a conversation without saying anything twice.
  • To prevent an exploit that would allow the player to seperate a student from other students by aiming a camera at that student’s face indefinitely, students will now only pose for 5 seconds maximum before stopping. Aiming a camera at a student’s face for longer than 5 seconds will annoy the student and result in a reputation penalty.
  • Replaced the interior of the school gym and fixed bug that would cause Yandere-chan to turn invisible / flicker while inside the gym. (Howevere, there is still no collision inside the gym yet).

  • Added more cherry blossom petals around areas where they would logically be found (on the hill with a cherry tree and at the two fountains east and west of the school entrance).
  • The player must now be less than 1 meter away from a student to attack them. (Previously, the player could attack from 2 meters away, which was super overpowered.)

2018 Builds

Date Changes
1/1/2018

  • Added a new accessory for Yandere-chan. Press the spacebar to change its color.
  • Added numerous new hairstyles for Yandere-chan.
  • Added a poetic easter egg in the Meme Closet.
1/12/2018
  • From now on, students who gather in a spot to socialize will not perform the “socializing” animation unless at least one other person is present. (As of now, this only applies to the Rainbow 6 and the Basu Sisters.)
  • Added a new accessory for Yandere-chan, in honor of a YouTuber who has helped to spread Yandere Sim to Brazil.
  • Compressed many textures in an attempt to lower the game’s file size and memory usage.
  • Re-colored a few parts of the GUI to suit the color scheme of the rest of the game.
  • Once again attempted to fix the bug that permits male students to be kidnapped.
  • Updated the Calendar screen to reflect the year that the game takes place in.
  • Slightly changed the appearance of the walkway area in front of the school.
  • Updated Mai Waifu’s hair so that some parts of it would not appear black.
  • The player can no longer move the camera during a pepper spray game over.
  • Added one new easter egg. (Activated with the “M” key in the Easter Egg menu. It’s a very simple and straightforward easter egg, but I hope it amuses you!)
1/13/2018
  • The faculty room is now a “trespass zone”, and teachers will react when Yandere-chan enters (but I still need to give them a different voiced line to say when Yandere-chan trespasses there).
  • A student will now get frustrated and stop talking to Yandere-chan if Yandere-chan repeatedly talks to them and then ends the conversation without saying anything.
  • If Yandere-chan looks bloody or insane and points her camera at a student, that student will no longer pose for Yandere-chan, and will now react negatively.

  • Made Slight tweaks to some of the Student Council girls’ textures.
  • Added one new hairstyle for Yandere-chan.
  • Restored Mei Mio’s bun hairstyle.
  • Enabled the “M” easter egg. (I accidentally created the previous build with the easter egg disabled.)
1/19/2018
  • Added “Hunger Mode” Easter Egg. This one works differently than others. In the beginning, you will move very slowly. *Each time you “eat”, you will gain speed.
  • To prevent bugs, Student Council members will now longer shove you or pepper spray you while an easter egg is active.
  • Replaced the “leaning left and right” animation with a more natural-looking animation.
  • The player can no longer get a Game Over from Senpai while an easter egg is active.
1/20/2018
  • Usually, when an easter egg is active, I disable the code that allows students to identify Yandere-chan as a murderer. This is so people can goof around with easter eggs without being stopped. However, for the Hunger Mode easter egg, I am allowing students to react to Yandere-chan and apprehend her; this is because the point of Hunger Mode is to challenge the player to stealthily take down students without getting caught in order to unlock powers that get stronger with each student who is consumed. (A cooler reward is something I’ll have to implement in the future.)
  • Attempted to reduce chance that martial arts club members would get stuck on each other while attempting to walk into the changing booth.
  • The student council will no longer react to Yandere-chan’s footsteps or shove Yandere-chan if an easter egg is active.
  • Adjusted Medusa easter egg so that students are only turned to stone if Yandere-chan is within their cone of vision.
  • Yandere-chan can no longer be punished for being late to class if her teacher hasn’t even arrived in class yet.

  • Added a new easter egg to the game – “Gazer Mode”.
2/2/2018
  • New Persona, Phone Addict.
  • Midori’s Persona has been changed to “Phone Addict”.
  • The 4 new characters are Musume’s friends, who follow the same fashion trends as Musume.
  • Musume’s friends accessorize much more than normal students; They each have unique phones, phone charms, bookbags, scrunchies on their wrists, cardigans around their waists, etc.
  • If a student’s reputation drops below -33, that student will be targeted for bullying. (If multiple students have a reputation below -33, the one with the lowest reputation is targeted.)
  • A bullied student will use a different walk animation / idle animation than other students, and have a different routine from other students.
  • If a student’s reputation drops below -100, the bullying will be so severe that they just won’t come to school anymore.
  • Once a day, there will be an event where Musume’s friends harass a student who has been targeted for bullying.
  • Musume’s friends will scribble graffiti on the desk of a student who has been targeted for bullying.
  • It is now possible to zoom in and zoom out with Yandere-chan’s smartphone even if the user doesn’t have a scroll wheel; just use the Tab and Left Shift keys. (Only works if the player is a member of the Photography Club.)
  • Any student who becomes “Broken” (currently, it’s only possible with Musume after kidnapping her and holding her hostage) will switch their Persona to the Coward Persona.
  • If a teacher is late to class (or is distracted by something during class), students will now perform a “Huh? What’s wrong?” animation in their seats.
  • Changing into a clean pair of shoes will now cause Yandere-chan to stop leaving bloody footprints on the ground.
  • Replaced some of the first weapon models (Knife, Syringe, Box Cutter, Screwdriver) with new, improved models.
  • Adjusted props in the infirmary room so that there wouldn’t be gaps between the furniture and the walls.
  • Removed the “ledge” running around the school’s rooftop; it didn’t really feel like a big improvement.
  • All female school uniforms are now “fitted”, like most anime school uniforms usually are.
  • Adjusted weapon colliders so that weapons wouldn’t float in midair above surfaces.
  • Adjusted the position of some props that appeared to be floating in midair.
  • A sound effect will now play when the player takes a photograph.
  • Improved the model/texture for the loose socks.
  • Added a special power to Hunger Mode, unlocked after the player feeds upon enough students.
  • Yandere-chan’s blood footprints now take the shape of bare feet in Hunger Mode.
  • Added voiced lines for Yandere-chan while feeding during Hunger Mode.
2/3/2018
  • Changed the school uniform that Info-chan uses in Mission Mode, since the school’s uniform is black in the “Mission Mode Timeline”.
  • Replaced the original placeholder phone model (a black cube) with the higher-quality phone model that is used during Osana’s events.
  • Removed debug command for testing an upcoming character model (pressing the spacebar would put every student into a lab coat).
  • Midori will no longer mutter to herself while texting; it was causing too many bugs.
  • Unfortunately, had to remove Mai Waifu’s custom eyes again; created too many bugs.
  • While I was creating the previous update, I changed Musume’s Student ID. This had more side-effects than I expected, and resulted in some new bugs. The quickest way to fix the problem was to simply implement a new student to take Musume’s old Student ID slot. So, I’ve implemented a new character to occupy that spot. However, don’t get too attached to her! She’ll be removed from the game once it’s time to implement the “Mysterious Obstacle”.
2/4/2018
  • If the player jumps directly to lunchtime at the beginning of the day, the game will automatically put graffiti on the desk of the student with the lowest reputation, without requiring the bullies to manually put it there.
  • A student who has been targeted for bullying will now be shy around cameras, and will perform a “hiding face” animation when you try to take a picture of them.
  • If multiple Phone Addicts are texting the police, the “Chase Camera” will follow the Phone Addict who is closest to finishing their text message.
  • It is no longer possible to give food to a member of the Student Council; they are too cautious to accept food from a stranger.
  • Graffiti that has been put on a student’s desk will be removed at Cleaning Time.
2/5/2018
  • Previously, if you sent a student to distract another student, and the target student entered a “Busy” state (like talking, for example) the original student would immediately return to their normal routine. From now on, a student will not break out of the “Distracting Target” state unless they visually confirm that another student is in a “Busy” state.
  • The player will no longer lose reputation points when gossiping with a bully, since bullies don’t frown upon gossip.
  • Improved the “sad sit” animation that is performed by a male student who is being bullied.
  • Changed the pose that a certain character was doing in her Student Info portrait.
  • Added one new hairstyle for Yandere-chan.
2/6/2018
  • Previously, I attempted to make it possible for female students to have long skirts. However, I wasn’t able to get it to work properly (a long skirt would always clip into the characters’ legs during their walk animation). Today, I came up with a possible solution to the problem, and it seems to be working. Presently, you will be able to see one student in school with a long skirt.
  • A bully can no longer be broken out of one of their bullying events by hearing a giggle from Yandere-chan. (However, a bully can still be broken out of a bullying event by seeing Yandere-chan covered in blood, carrying a weapon, acting insane, etc.)
  • If Yandere-chan causes a disruption that breaks a bully out of their bullying event, the bully will remark about how Yandere-chan “killed the mood”, and then the bully will leave the area.
  • A student’s “bullied” animations will now take priority over their “shy” animations.
  • Adjusted the way that male students hold their phones.
2/7/2018
  • If someone takes a photo of you committing murder, but you’re wearing a mask in the photo, you will no longer get an instant game over, since the cops won’t be able to identify you from the photo. (They’ll still come to school, though.)
  • It is now possible to make bullies prematurely end a bullying event by having a another student show up and talk to the bullied student.
  • Adjusted height of trees and bushes around the school so they are no longer floating slightly above the ground.
  • Adjusted the “Chase Camera” that appears when a student is texting a photo of your crimes to the cops.
  • It is now possible to take a panty shot of the school nurse.
2/20/2018
  • Reverted Horuda’s skirt back to being a short skirt, because the code used to lengthen her skirt created too many unfortunate side-effects. (It would be better to create a new character model designed to have a variable skirt, rather than use workarounds to manually lengthen the skirt of a model that wasn’t designed to support that kind of functionality.)
  • The “empty husk” in the Art Club has been replaced by the Art Club’s leader, Geiju. (The player can interact with him, and he has voiced lines, but he will not react to murder or anything like that, so he’s not very different from an “empty husk” at this point.)
  • Killing a student with a blunt object stealth attack (neck snap) will no longer cause the student to spawn blood pools (since there is no open wound).
  • Yandere-chan now plays new animations when she’s around Senpai. Her animations will get progressively creepier the more time she spends around him.
  • Covered up the little gaps on the rooftop that would allow you to look down into the rooms underneath the rooftop (and a few other gaps too).
  • The Student Council will no longer react to footsteps when Pose Mode is active, since it interferes with the player’s ability to pose them.
  • The player will no longer hear sound effects (such as the incinerator burning something) when the end-of-day text is displaying onscreen.
  • The panties that you choose while in Yandere-chan’s room will now actually appear on her character model when at school.
  • There are now 5 “ambient conversations” that occur at school between male students – one for each day of the week.
  • The mouse cursor is no longer hidden when entering a Mission ID into the Load Mission screen in Mission Mode.
  • The little blood-cleaning robot in the Science Club now has an outline when Yandere Vision is active.
  • A character whose family member has died will now have a depressed walk / depressed idle animation.
  • Added the ability to decorate Yandere-chan’s corkboard at home with red strings.
  • It is now possible for randomly-generated students to be Phone Addicts.
  • Pippi and Ryuto now have the Phone Addict Persona.
  • Made Yandere-chan’s Miku hair more floaty.
  • Added one new hairstyle for Yandere-chan.
  • Populated the Art Club with props.
  • Added a Kill La Kill easter egg. It’s pretty basic for now, but maybe one day I’ll give it more depth.
2/21/18
  • The cursor on the corkboard now moves at a slower speed when playing the game with a keyboard (but it still moves at the same speed when using a mouse or a controller).
  • Adjusted some of the images in the Art Club so that they wouldn’t flicker when the player moved their camera around.
  • Improved some of the paintings in the Art Club.
3/6/18
  • If two students in a “mind-broken” state are both trying to kill the same target, the second mind-broken student to reach the target will commit suicide as soon as the first mind-broken student begins the murder-suicide animation.
  • It is now possible to “Tag” a student from their Student Info page so that a marker appears around their head in Yandere Vision. This is to help the player when they are trying to quickly locate a specific student.
  • The “Evil” Persona has been changed into the “Spiteful” persona. Instead of enjoying all deaths, a Spiteful student only enjoys the death of a student who has been bullying them, or the death of a bullied student.
  • It is now possible to change Yandere-chan’s “Persona” at any mirror (including the ones in bathrooms or the locker room). Using different Personas will grant you benefits will certain groups of students.
  • Added a new set of background tracks to the game (3 different tracks for each level of sanity during high atmosphere, medium atmosphere, and low atmosphere; 9 tracks in total).
  • The police will no longer arrive at school when an easter egg is active. (The Police timer will appear, but no police will arrive.)
  • Reduced the reputation boost that the player gets from handing out food, because it was too imbalanced.
  • “Dangerous” and “Heroic” students are no longer able to switch to the Phone Addict Persona.
  • The corkboard will now recall photographs and strings across multiple days.
  • Removed duplicate knife that wasn’t supposed to be in the Cooking Club.
  • Double-tapping the “M” key will now change the background music.
  • Improved bully cardigan textures.
  • Improved Yanketsu texture.
  • Improved Ebola textures.
3/15/2018
  • The player can now use Info-chan’s Services menu to increase their reputation, decrease their rival’s reputation, obtain information about a student, and delay the police when they are en route to school.
  • Kokona will now react to Yandere-chan eavesdropping on her private Monday phone call. (This is relevant because Osana’s phone call event uses the same code.)
  • Decorated the incinerator area with a few props, since it’s going to receive more focus in the near future. It’s definitely not finished, though.
  • There is now an “Eavesdropping” warning at the top of the screen when Yandere-chan is eavesdropping on a private conversation.
  • Students will now react negatively if they spot Yandere-chan eavesdropping on another student’s private conversation.
  • Aiming a camera at a bully who is bullying a student will now cause the bully to prematurely end the bullying event.
  • There is now a DDR-style dance machine somewhere on school grounds. Eventually, I’ll explain its purpose.
  • Re-named “Bookworm Persona” to “Scholarly Persona” because “Bookworm” was a very poor choice of words.
  • The player can no longer talk to a character who is in the middle of an event.
  • From now on, students will investigate screams instead of ignoring them.
  • As of now, if all bullies are dead, a student can no longer be bullied.
  • Updated the warning text that displays after launching the game.
  • The player can now apologize for eavesdropping.
  • Added some new props near the shoe locker area.
  • Added a few decorations to the Gaming Club.
  • Added a new cassette tape to the game. There aren’t any huge plot twists in this tape, but it sets the stage for some future twists.
3/31/2018
  • Replaced the giggles in the Low Reputation Game Over sequence with new giggles that don’t sound like squeak toys.
  • If neither Sakyu nor Inkyu are attending school, Oka will no longer go to the rooftop and try to spy on them.
  • Added a few new models to the rooftop, strategically placed for upcoming tactical espionage action gameplay.
  • Replaced Kuu Dere’s hair model with a new one, because the original model had strange visual bugs occurring.
  • The player can now use Info-chan’s Services menu to make a student leave school for the rest of the day.
  • Updated the trophy cases at the front of the school so that they’re not duplicates of each other.
  • Changed the floor/wall/ceiling textures of the Science Club (it’s not finished yet, though).
  • Updated the dance machine model. (Still not ready to elaborate about its purpose yet.)
  • Improved the appearance of some of the walls and pillars outside of the school.
  • Restored previous walk animation for Yandere-chan’s “Graceful” Persona.
  • Updated the appearance of the school plaza on the title screen.
  • Added a new hairstyle for Yandere-chan.
  • Added another Headmaster tape.
  • I’ve put a couple of props into the Photography Club. I’m using that club as a testing ground for new models, so if you see weird stuff in there, don’t mind it too much. The weird props will be moved to other locations eventually.
4/2/2018
  • Info-chan will now refuse to perform the "Send Student Home" service if a student is preoccupied with something that would logically prevent them from caring about checking their text messages.

Added a small amount of functionality to a model in the Science Club. It doesn’t do anything significant for now…but that might change in the future.

  • Restored something that has been gone for a long time.
4/26/2018
  • Added new delinquents.
  • Added combat mini-game.
  • Previously, if the player used Pose Mode to move a student inside of an object (like a tree) the player would lose the ability to interact with that student, potentially ruining poses. As of now, activating Pose Mode will cause the game to ignore colliders so that the player can interact with students even if there is a collider between Yandere-chan and the student (or if the student is inside of a collider).
  • Rim lighting, color grading, ambient obscurance, and distant background mountains are now enabled by default. The player has been given the option of disabling any of these things in the settings menu.
  • Added two more background tracks to the game (each with 9 variations, one for each combination of school atmosphere and sanity).
  • It is now possible to release a student from Pose Mode and let them continue their routine after you’ve customized them.
  • Updated the “receiving an alarming text message” animation that plays when the player uses the “Send Home” feature.
  • Added some models to the Announcement Room, although some further work still remains to be done.
  • Replaced Kuu Dere’s new hair model with another one that isn’t as bright and flashy.
  • Added shading to Oka’s stockings / arm-warmers.
  • Added a few more props to the Science Club.
  • Added a new sword to the Drama Club.
  • Tweaked Mai Waifu’s hair color.
  • Added another Headmaster tape.
  • Improved 6 old hair models.
4/27/2018
  • The button prompts that appear during the combat minigame should now be more crisp and clear and easy-to-read, even when the game is being played at a low texture resolution.
  • Added some props to the Science Club in preparation for upcoming characters who will be interacting with those props. (Some of the props are not final yet.)
  • Removed the ability to spawn a time portal to 1989.
  • Gave Senpai a voiced line for witnessing violence (still needs a unique animation, though).
  • Removed debug command for summoning the old delinquents.
  • Bullies will no longer attempt to bully delinquents.
4/28/2018
  • From now on, a delinquent’s fingerprints will be on his weapon from the start of the day, rather than only appearing on his weapon when he grabbed it. (Logically, he had to get his fingerprints on his weapon while putting it in his bag before going to school.)
  • Delinquents will no longer bust out their smartphones and start texting immediately after winning a fight.
4/29/2018
  • Delinquents now start out with lower reputations than other students (and if you try to raise their reputations, their reputations will always reset back to a low number at the beginning of each day).
  • A character who has been startled by another character’s scream will now become more alert (they will notice corpses / behavior from further away).
  • Rotated one of the trophy cases near the locker area, since it was actually facing the wall.
  • Bullies will now refuse to perform the “Distract” favor on a Delinquent.
  • Delinquents will now react differently to the corpse of a bully.
4/30/2018
  • From now on, if you disable rim light / distance blur, the game will remember your preferences and will disable rim light / distance blur in the future. (But when you reset the week, your preferences will be reset, too.)
  • Delinquents will no longer continue to perform their attack animation if Yandere-chan is apprehended by a teacher in the middle of a fight.
  • Delinquents will no longer accept food from Yandere-chan (if she offers them food, they’ll respond with a rude, dismissive remark).
  • Kokona was moved to a different seat in a recent build, so her bookbag has been re-located to her new seat.
  • Kokona will now show signs of attraction to the delinquents, since she is attracted to piercings.
5/2/2018
  • To make it much easier to develop the game, I needed to add a debug command that would allow me to activate / deactivate specific students whenever I choose. I decided to create a menu for it, and I’m very satisfied with how it turned out. In order to access this new menu, look behind the tree that is to the left of Yandere-chan when she goes to school.
  • The two sparring students in the Martial Arts club will now actually perform a sparring animation instead of just standing there motionless.
  • If you get too close to the two sparring students in the Martial Arts Club, they’ll stop sparring, tell you that you’re in the way, and wait for you to move to a safe distance before they resume fighting.
  • If you open the debug menu and press “0” to disable the secondary first-person camera, the background behind Yandere-chan’s hands will now be black instead of pink.
  • There should no longer be weird artifacts appearing at the top/bottom of the screen when the player is playing the game at an aspect ratio other than 16:9.
  • From now on, when a Rainbow Six girl is sitting in the Cooking Club alone, she will text on her phone instead of talking to thin air.
  • Adjusted the position of smartphones in female students’ hands so that the phones weren’t being held at strange, extreme angles.
  • Updated the hair physics for two hairstyles which had weird clipping going on whenever the hair moved.
  • Added a new easter egg to the Meme Closet. This easter egg is dedicated to a wonderful YouTuber who has been making Yandere Simulator videos for a long, long time!
5/3/2018
  • A few days ago, I updated the Characters page on the official website with a new character. I didn’t announce it because the website wasn’t updating for me, so I couldn’t actually tell if he had been added to the site or not. Anyway, now it’s working for me, so I can announce that the Characters page has a new addition! By the way, that character’s artwork was updated today, so if you saw him before, you might want to look again.
  • Fixed exploit that would allow the player to very easily make a character stand in one spot for a long period of time by continuously aiming a camera at their face to repeatedly invoke their “posing for camera” pose.
  • It is no longer possible to use the “Rest in Infirmary” feature under any circumstances where the player wouldn’t be able to attend class (with a dead body lying on school grounds, for example).
  • It’s no longer possible to use Info-chan’s “Send Home” service on a student who is in the middle of a scripted event (such as the two boys talking about anime at lunchtime).
  • The phone that Yandere-chan holds when she is using the Pass Time feature is now her normal smartphone, rather than the old primitive placeholder smartphone.
  • It is now possible to rotate the camera in the Senpai Creation Screen by using the mouse (or the right joystick if you’re using a controller).
  • Yandere-chan is no longer able to drag or carry a corpse if that corpse is on fire. (She has to wait until the corpse stops burning.)
  • The “Debug Demon” is now disabled during Mission Mode, since debug features are supposed to be disabled during Mission Mode.
  • Added collision boxes for many objects in the faculty room / meeting room that did not have collision.
  • It is now possible to put the delinquents’ hairstyles on Senpai in the Senpai Creation Screen.
5/4/2018
  • From now on, a delinquent who was injured and dropped his weapon earlier in the day will no longer try to take down Yandere-chan with his bare hands; instead, he will flee the school while swearing revenge.
  • The delinquents will now say different voiced lines when chasing down the player after the player has already defeated them in a fight earlier in the day.
  • If a student has been sent to distract a target, they will stop if their target has become busy performing an action (such as changing their shoes).
  • The delinquents will now say a voiced line at the beginning of a fight. (These lines are subject to change in the future.)
  • Fixed end-of-day police investigation text that referred to a male victim by a female pronoun.
5/6/2018
  • If a Teacher’s Pet witnesses murder and reports it to a teacher, but the teacher can’t find any trace of a murder and thinks it’s a prank, the Teacher’s Pet will use a traumatized idle/walk animation for the rest of the day, and will no longer perform cheerful socializing animations.
  • Students will now refuse to distract the delinquents, because nobody wants to go near them.
  • The player can now find additional bleach in the gardening shed.
  • A bullied student will no longer agree to distract a bully.
5/10/2018
  • Yandere-chan can no longer perform certain types of actions while a delinquent is about to start chasing her. This means that, if a delinquent has witnessed her commit murder, has been defeated in the combat minigame, and is catching his breath for a few moments before he begins to chase her, she can no longer perform any action that puts her into a “state” that only ends once an animation has finished playing. For example, the “sit down at sewing machine and sew a uniform” state, which ends once the sewing animation has ended.
  • Delinquents now sound much different when reacting to the sight of a corpse. (Previously, they were releasing a blood-curdling terrified scream of pure horror, which doesn’t really suit a bunch of tough guys).
  • Adjusted one of the sound-dampening black foam walls in the Announcement Room’s recording booth so that it doesn’t clip through the wall and become visible on the adjacent stairway.
  • Adjusted all of Senpai’s game over animations where he would take multiple steps backwards and clip into whatever objects / walls were behind him.
  • Adjusted “delinquent loses combat minigame” animation so that their right arms aren’t posed at such odd angles when they loses a fight.
  • Edited “refuse to distract student” text to use gender-neutral phrasing so that it can work with both male and female students.
  • Made progress towards adding the Science Club to the game. Visit the science clubroom to see a preview of upcoming characters!
  • Replaced old “getting into fight” delinquent voiced lines with louder, faster, more aggressive versions of those lines.
  • Delinquents now have voiced lines when noticing a bully’s corpse and running away from it.
  • Updated the appearance of the gate outside of the entrance to the school.
  • Added “witnessed Yandere-chan having a fight” animation for Senpai.
  • Updated the look-and-feel of the official website! Check it out!
  • Added one new hairstyle for Yandere-chan.
  • Added Enigma Mode.
5/11/2018
  • The player can no longer perform a club activity immediately after sending a mind-broken slave to kill someone.
5/13/2018
  • Updated the appearance of the Photography Club. It’s not finished yet; I still need to spend another day or two on it to bring it to completion – then I’ll be ready to add the Photography clubmembers and the “Sleuth” Presona to the game!
  • Added two new hairstyles for Yandere-chan.
  • Slightly updated Cirno Mode textures.
5/14/2018
  • Performed more work on the Photography Club’s clubroom. I’m still not done working on it, but if you take a second look at it now, you may understand it a bit better.
  • When they are alone, delinquents now use an updated “texting on smartphone” animation that looks much more appropriate for a “tough guy” type of character.
  • Musume now loses the “Phone Addict” persona and switches to the “Coward” persona after being kidnapped and held for ransom.
  • Male students’ hands will no longer clip into their phones when they are checking their phones before class begins.
  • Way back on June 3rd, 2015, I implemented the “Bancho” easter egg. Recently, I accidentally activated this easter egg while trying to use a debug command, and saw it for the first time in years. I realized that it’s incredibly boring – it doesn’t even have any sort of functionality or attack associated with it! I decided to spice it up with a new appearance, new animations, and an attack animation. It’s very similar in nature to other easter eggs we’ve had in the past, but still, I couldn’t resist updating it; I didn’t want to leave Bancho Mode in such a boring state.
5/15/2018
  • Female students will now use a different animation when texting on their phones; the previous “ditzy, carefree, air-headed” texting animation was only meant to be used by Midori.
  • Updated the icons that appear in the “Challenges” section of the Calendar screen. (Bet you forgot all about that screen, huh?)
  • Delinquents will no longer stop and pose for a photo if you aim your camera at them while you’re in the Photography Club.
  • Made further adjustments to the Photography Club (it’s still not done yet).
5/18/2018
  • Changed the wording of the text that displays when a club disbands because of a dead club leader so that it applies to more types of circumstances.
  • Cowards will no longer use the Phone Addict reaction to murder if they are holding a smartphone when they witness a murder.
  • Adjusted the rotation of the doors in the plaza area so that they won’t clip into the hedges near the walls of the plaza.
  • Added a few more props to the Announcement Room.
6/1/2018
  • Added 5 new characters and two new Personas.
  • Added some props to one of the gym storage rooms
6/2/2018
  • Added a little bit more space between lines when talking to a Club Leader so that their sentences don’t begin too quickly after their previous lines.
  • Changed Rojasu’s surname (his previous surname was a typo).
6/3/2018
  • Updated the Sleuth Persona’s “investigate” animation so that it looks more natural, and made them stand farther away from their targets so that they look like they’re checking out the vicinity rather than closely examining one person.
  • Gave the Photography Club new “carefree talking” and “serious talking” animations that might feel a little more natural.
  • Adjusted Rojasu’s animations a bit to give him that “chill” vibe I was going for.
  • Tweaked Horuda’s portrait.
6/5/2018
  • When a female student is standing while texting on a smartphone, the smartphone should no longer be tilted at a strange angle.
  • Adjusted the headmaster’s code so that when he rotates to face Yandere-chan, his movements look more natural.
  • Updated the “burning to death” animation for male students so they close their eyes at the end.
  • Students should no longer get stuck on doors when trying to pass through a doorway.
6/7/2018
  • Changed some of the Photography Club’s poses in their student portraits (but I will probably continue to tweak Rojasu and Sukubi’s poses and expressions, since I’m not satisfied with them yet).
  • Removed debug commands from the Welcome scene (the first scene that displays when you launch the game) because some people were activating those commands by accident and getting confused.
  • Updated Senpai’s “reacting to creepy behavior from Yandere-chan” game over animation so he doesn’t step so far backwards, to prevent him from clipping into any props or walls behind him.
  • Heroic students will now sprint to the source of a scream as soon as they hear one, instead of pausing for several seconds and then walking slowly to the source of the scream.
  • Updated the Photography Club’s textures to give them color schemes that are less derivative of pre-existing characters with similar hairstyles.
  • Added buildings in the distance outside of the school to represent the small town that is supposed to be outside of Akademi High.
  • Updated the colliders of the school’s stairways so that it doesn’t feel like there are invisible walls near the stairways.
  • Adjusted the size of Beruma’s glasses.
7/1/2018
  • Added another set of background tracks to the game, one for each combination of sanity and atmosphere – a total of 9 new tracks! It’s the 6th set of background tracks added to the game.
  • You can now use the “Void Goddess” (spider demon lady) to teleport students to your position, for testing / debugging features that require certain characters being present in a specific location to witness certain things.
  • Adjusted chair colliders in classrooms so that students should no longer be able to get stuck on their chairs when trying to leave their classrooms / sit down at their seats.
  • Added an extra curtain entrance to the Photography Club’s hangout so that they can no longer be blocked from entering their own hangout by Yandere-chan.
  • Adjusted pathfinding timing so that students don’t frequently change course all the time (less robotic behavior, more fluid and human behavior).
  • Added 15 new characters and gave them routines that involve interacting with various new props placed around the school.
  • Added collision boxes to the school gym, so the player can no longer walk through the walls.
  • Added Fureddo’s armband to his student portrait.
  • Improved Yandere-chan’s “Ibuki” hair model.
  • Added two news hairstyle for Yandere-chan.
  • Improved Rojasu and Sukubi’s portraits.
  • Added functional doors to the gym.
7/2/2018
  • The player can now activate a club leader’s club-related dialogue options by speaking to them whenever they are within 10 meters of their club routine area, instead of having to speak to them when they are standing still inside of their club.
  • The club characters will now stop holding props in their hands when the player has aimed a camera at their faces.
  • If a delinquent sees Yandere-chan holding a bully’s corpse, they will now react with the “Evil Persona” reaction.
  • Removed the nameplates that were mistakenly placed inside of the gym’s storage rooms.
  • Restored missing geometry on the exterior of the school gym.
  • Adjusted a few characters’ personas.
7/3/2018
  • To make sure that his profile description (“a man of few words”) matches his behavior, Geiju now speaks exclusively in extremely short, apathetic, one-word or two-word sentences when interacting with Yandere-chan.
  • Adjusted the Student Information box so that text can’t be right up against the borders of the box.
  • Updated Geiju’s portrait to accurately reflect the color of his glasses.
  • Removed some expensive debug calls that were lowering the framerate.
  • Fixed typos in student profiles.
7/4/2018
  • Students should no longer be able to get stuck on open doors on the school’s rooftop.
  • Geiju will now say a shorter sentence when reacting to Yandere-chan’s misbehavior.
7/13/2018
  • Decorated the bullies’ bags with stickers and pins.
  • Updated Kaga’s hair model and portrait.
7/18/2018
  • In order to prevent the player from accidentally resetting the day when they didn’t mean to, the “Reset Day” debug command now requires the player to hold down the “~” key for 1 second, instead of tapping it.
  • If you press the “L” key at the Settings menu, all settings will drop to the lowest level. This will improve the framerate. (If you press “L” and then turn on anti-aliasing, it actually looks pretty okay!)
  • When the player is spotted in Mission Mode, a text box will now inform the player of exactly which student spotted them.
  • The Settings menu now allows the player to change the sensitivity of the camera.
  • Added one new hairstyle for Yandere-chan.
7/24/2018
  • Added another background track to the school; now there are 7 different tracks you might hear while walking around school. (And each of those tracks has a variation for every combination of sanity/atmosphere.)
  • Changed the layout of the exterior of the school so that the pool, gym, and running track are closer together, and located closer to the shower areas.
  • Temporarily disabled depth-of-field, since it was causing a bug where objects would become blurry if viewed in front of a transparent object.
  • Added a text box to the Custom Music menu with instructions so that people will be able to understand how to use it properly.
  • Added some posters on the hallways.
  • Changed the backdrop outside of the school.
  • It’s no longer possible for Yandere-chan to exit the locker room while she is nude.
  • Added a shower area for male students.
  • Added 5 new students to the game – the Sports Club!
  • In the morning, they jog on the school’s running track. In the afternoon, they swim in the school pool.
  • Their daily routine involves changing into two different outfits (a jogging tracksuit and swimming trunks).
  • Their club activities involve 7 different animations, way more than most other students, who usually only have about 1 or 2 club-related animations.
  • When they dive into water, their hair gets wet, and their hair model changes shape to reflect the fact that their hair has become soaking wet.
  • Each member of the Sports Club has a different level of strength, and when they take off their clothing, the player can see different levels of muscle definition on their bodies.
7/25/2018
  • Attempted to improve pathfinding so that Sports Club members won’t take shortcuts across the grass field when running on the track behind the school.
  • Sports Club students will no longer attempt to use the same ladder as other students when climbing out of the pool.
  • Changed the text that displays on the Student Info screen when a student’s strength is the maximum value.
  • Reduced length of one of the Sports Club stretching animations.
8/18/2018
  • Added 9 new characters to the game.
  • Added 2 new clubs to the game – Cooking and Drama. (Arguably, it’s 3 new clubs, since the Gaming Club has completely changed).
  • Added 1 new task to the game. This is the first task that has utility outside of simply befriending a student; it impacts other characters’ routines.
  • It is no longer possible to activate “High School Population” mode, since it was a feature that always required a lot of maintenance, and it’s no longer necessary, since the school’s population is pretty high as it already is.
  • When talking to a club leader in a clubroom, it is now possible to switch from discussing the club to discussing other topics by pressing the “F” key (or the X button on Xbox controller).
  • A fragile student will no longer agree to meet you to discuss bullying in a classroom; they’ll only agree to meet you in a place with few people (like behind the school or the rooftop).
  • It is no longer possible for Nemesis to disguise herself as a club leader, since it could prevent the player from being able to join a club they need to join in Mission Mode.
  • Removed Oka Ruto from the game and made Shin Higaku the president of the Occult Club.
  • Removed the “Rainbow Girls” and “Rainbow Boys” except for Kokona, Riku, and Saki.
  • Musume’s task is now available after cleaning time, instead of during lunchtime.
  • The Sports Club will now eat lunch nearby the pool as part of their routine.

  • Added new props to the backstage area of the school gym.
  • Updated the appearance of male gym uniforms.
  • Improved the “playing video games” animation.
  • Changed the Gaming Club accessory to a red cloth. (Every clubmember wears their cloth differently.)
  • The “play a video game” feature has been moved from the computer lab into the new Gaming Club room.
  • The Gaming Club has been moved to a different room in the school, and has been furnished with props.
  • The Gaming Club students now walk around school, playing an “augmented reality” game on their smartphones.
  • Yandere-chan can now view “augmented reality” on her smartphone in order to see where the Gaming Club is heading next.
  • Yandere-chan can also “play” the augmented reality game; she can shoot energy blasts to kill virtual monsters, which will cause the Gaming Club to change course and head in a different direction.
8/19/2018
  • Previously, if you annoyed a student by repeatedly talking to them / wasting their time, they would ignore you for the rest of the day. Now, they will only ignore you for a few hours (after you’ve passed time in class).
  • From now on, if a Phone Addict witnesses you commit murder in the span of time *after* they have taken a photo, but *before* they begin fleeing, they will snap another photo.
  • When joining the Gaming Club, Yandere-chan will now wear a red cloth instead of a D-pad in her hair, like the rest of the members of the club.
  • Disabled the cinematic camera’s ability to see the “augmented reality” models, so that the magical girls don’t photobomb your screenshots.
  • Lowered the volume of the latest set of background tracks, since they were much louder than the rest of the game’s music.
  • Distributed different Personas to some of the students, since the ones in the previous build were placeholders.

9/3/2018
  • It is now possible to learn a student’s opinions on various topics by befriending the student, then asking them to follow you around school, and then walking by various important locations (such as clubrooms, library, incinerator, etc). As of now, only Kokona has opinions on topics, but other students will be updated with opinions evenutally.
  • To make it clear that the player must befriend Kokona in order to be able to use the “Offer Help” command, the text “Must Befriend Student First” now appears when attempting to offer help to Kokona before befriending her.
  • When I changed Kokona’s StudentID number, various features related to Kokona became broken. These features should now be fixed.

10/14/2018
  • Changed render settings that should drastically improve the framerate. In the previous build, the lowest framerate I was able to get was 20, but in the current build, the lowest I can get is 27!
  • Changed shader for the pool’s water so that it shouldn’t flicker in strange ways when the player adjusts the camera angle.
  • Updated facial expression on walk animation for female students so that they don’t all have “resting bitchface”.
  • There is now a bucket of red paint in the Art Club. The player can use this bucket to splatter themselves with red paint to give themselves the appearance of being splattered with blood. There is a reason to do this, but instead of describing it, I’d like to see who can figure it out.
  • If a teacher catches the player misbehaving, they are sent to the guidance counselor.
  • In the guidance counselor’s office, the player is given several dialogue options, and must figure out which one will get them out of trouble (or result in the least-harsh punishment).
  • After hearing the player speak, the guidance counselor will either let you go, suspend you for a number of days, or expel you outright.
  • The guidance counselor has around 80 different voiced lines that can be heard while the player is in her office!
  • One of the player’s potential dialogue options is locked at the beginning of the game, and must be unlocked before it can be used.

  • The Light Music Club members walk around with instruments, and practice playing their instruments in secluded spots so that they don’t pester anyone.

10/24/2018
  • Unconfirmed, but may have improved framerate
  • Added a new easter egg. You activate it by typing two words during gameplay. The first word is a synonym for “boat” and the second word is a synonym for “female”.
10/31/2018
  • Fixed visuals for a very rare End-of-Day scenario; if the police arrest someone for murder, and then notice blood on Yandere-chan’s uniform, she can convince the police that the victim’s blood was splattered on her uniform when the murder took place.
  • Updated walking/standing animations so that now certain characters have “friendly” expressions and other characters have “unfriendly” expressions.
  • Updated a few character portraits so that some characters are smiling and some are frowning, depending on their personality descriptions.

  • From now on, if Yandere-chan is eavesdropping on a student, the act of eavesdropping will only be suspicious to the person who is having a private conversation.
  • Itachi now uses a different texting animation than other students (he’s a moody character, so he needs a moody-looking animation).
  • Slightly adjusted the appearance of the Student profile screen; the screen now displays what class a student is in.
  • Geiju will no longer attempt to enter the Art Club during Cleaning Time if the Art Club has been shut down.
  • Kokona will no longer try to prepare food in the Cooking Club if the Cooking Club has been shut down.

12/5/2018
  • From now on, when you take a photo of something that has a use for Yandere-chan (like a photo of panties), a text box will appear at the top of the screen and display the name of whatever you have just photographed. If you take a photo of a Task-related subject (such as the kitten, or Miyuji playing air guitar) you’ll see the name of that subject appear at the top of the screen, too. This should help the player to confirm that they have taken a photograph of something that satisfies the requirements of a Task.
  • From now on, whenever you speak to a student, all Light Music Club members’ instruments will decrease in volume so that the sound of their instruments doesn’t overpower the voice of the student you’re speaking to. Their volume will return to normal when you stop speaking to the student.
  • Thanks to help from AMZE, female characters now have more distinct faces. As of now, no two female characters have a 100% identical face, although there are characters with very similar faces (within 1% of one another). Their current faces are not necessarily final, and may continue to change in the future.
  • Fixed the camera that provides a view of an object striking Kokona after it has been dropped from the roof (press “Q” when dropping something on Kokona to see this camera).

  • Made further adjustments to the pathfinding grid to make it even less likely for students to get stuck on doors when passing through doorways.
  • The Matchmaking minigame involved a reference to Kokona’s stockings, but she’s no longer wearing stockings, so I’ve removed that reference.

  • Added vegetables to the empty gardening plots in the Gardening Club, in preparation for improving the gardening club members’ routines by giving them more actions to perform aside from “watering flowers”.
  • Updated the appearance of the TV + TV stand in the Gaming clubroom so it’s not a duplicate of the TV + TV stand from Yandere-chan’s home.
  • Updated the artwork for the club recruitment posters near the school’s entrance. The new artwork was illustrated by Neronda!

2019 Builds

Date Changes
1/1/2019
  • Added another background track to the school scene (with 9 variations, one for each combination of atmosphere and sanity), made by Ferret Entertainment! The school scene now has 8 tracks in total. During school gameplay, you can skip to the next track by tapping the “M” key twice.
  • Removed Study-kun A and Study-kun B. Their purpose was to allow the player to deduce what Kokona was attracted to (slick hair, intelligence) but now that the school has other male students with those traits, the Study-kuns are no longer necessary.
  • Added two new background music tracks to Mission Mode (there are now 8 tracks in total). You can change the music that plays in Mission Mode by opening the pause screen and selecting the music icon during Mission Mode gameplay.
  • Upgraded the music being played by the Light Music Club when they practice around 5:00 PM. The new track was provided by David Area Williams of DIAVImusic
  • From now on, whenever the police identify a student’s corpse, the following day will begin with a memorial service for the deceased student.
  • From now on, if Kokona is in a relationship with Riku, she will no longer turn her head and check out other guys she finds attractive.

  • Yandere-chan will now begin Mission Mode with a single stat point in all of her stats.
1/15/2019
  • When aiming Yandere-chan’s camera, you can now switch to a “selfie” camera angle. The selfie angle allows you to be more discreet when taking a photo, because bystanders will assume that you’re taking a photo of yourself, rather than their face or their panties. In the selfie angle, your goal is to take a photograph of something to the side of Yandere-chan, rather than directly in the center of the screen. You can press a button to activate a little guide that shows you where your target should be located on the screen.
  • It is now possible to open/close the school gate by pressing a button near the spot where the gym teacher stands in the morning. You cannot press the button if the gym teacher is nearby.
  • Added a Japanese-style garden area nearby the incinerator area. It’s an experiment, and I might decide to resize it / redesign it / move it elsewhere in the future.
  • When pushing/pulling the dumpster, it is now possible to use the arrow keys in addition to the WASD keys or control stick.
  • Dumbbells now have unique combat animations, instead of re-using the baseball bat animation set.
  • From now on, whenever Yandere-chan performs a Task for a student, her reputation will increase.
  • Added new attack animations for the dumbbells. (Current sound effects are placeholders.)
  • Adjusted the appearance of the cafeteria area.

  • Added “Now Loading” text when reloading a mission in Mission Mode.
  • Added a couple of new hairstyles for Yandere-chan.

  • One of the new characters has a task. If you complete his task, he will provide you with one spare uniform per day.
  • One of the new characters trips and falls at the entrance of the school. When he falls, his head lands right where the school gate is. If you time it properly, you can squash his head by pushing the button that closes the gate right before he trips and falls.
1/17/2019

  • Added some new props to the Sewing Club.
  • It’s no longer possible to crawl while in Selfie Mode.
  • Fixed typos in student profiles.
  • There are now 4 types of poison in the game: Emetic, Lethal, Sedative, and Headache.
  • At lunchtime, Toga Tabara eats a bento at the school cafeteria. If you distract him with a giggle, he will put his bento down and investigate the giggle. When he’s not looking at his bento, you can put any of the 4 types of poison into it.
  • If Toga consumes emetic poison, he will go the bathroom and vomit. His appetite will be gone, so he will return to class early.
  • If Toga consumes lethal poison, he will die.
  • If Toga consumes a sedative, he will become drowsy and go to the infirmary to nap. He’ll return to normal once it’s time to return to class.
  • The “Headache” poison is for an upcoming feature. It currently serves no purpose whatsoever, but it’s going to be an important core gameplay mechanic in the near future
2/1/2019
  • A student who needs to vomit will now travel to the *nearest* toilet, instead of traveling to one specific toilet every time.
  • If a student sees you poisoning their food, you will lose reputation, and they will refuse to eat the food.
  • Students will no longer ignore murder or corpses if they are eating emetically-poisoned food.
  • If a student sees you poisoning somebody else’s food, you will lose reputation.
  • Students will now react to the sight of a student who is dying from poison.
  • It’s now possible to drown a student who is vomitting into a toilet.
  • Vomitting students will now make vomitting sound effects.
  • Horuda now eats lunch in the school cafeteria, facing Toga. This is to give players a good location for testing how students react to seeing someone die from poison, testing a student’s reaction to murder during a poison animation, etc.
  • If you put a headache-inducing substance into a student’s bento, that student will visit the nurse and ask for medicine to numb the pain. This will cause the nurse to visit the medicine cabinet and retrieve some pills for the student. The student will eat the pills and then spend time resting on the couch in the infirmary until their headache goes away.
  • The tranquilizer that is used to kidnap students is now inside of the infirmary’s medicine cabinet. The only way to obtain the tranquilizer is to give a student a headache so that they go to the nurse and make the nurse open the medicine cabinet.
  • Drinking fountains have been added to the school, and it is possible for Yandere-chan to use the water from these fountains to wash the blood off of weapons.
  • Yandere-chan can now find a large, heavy pipe wrench in one of the school’s storage rooms. This wrench can be used as a murder weapon, but can also be used to sabotage the pipes underneath drinking fountains, which creates water puddles.
  • Yandere-chan can now find a power strip in the A/V Room. This power strip can be plugged into any wall sockets that you might find. After plugging a power strip into a wall socket, Yandere-chan can use a screwdriver to expose the wiring of the power strip.
  • If Yandere-chan flips a switch that activates a wall socket while a sabotaged power strip is in a puddle of water, the puddle will become electrified and will electrocute anyone who stands in it.
  • There is now a new vending machine in school that allows Yandere-chan to purchase a bag of chips. Yandere-chan can offer the chips to any student in school. After eating the chips, the student will become thirsty, and will go to the nearest drinking fountain to drink water.
  • Most Students’ lunchtime routines have been adjusted. They now sit and eat lunch together. (In the future, I may decide to change the locations where they eat food.)
  • From now on, whenever the player attempts to attend class during circumstances when it’s not possible to do so (because the player is holding a bloody weapon or something like that) a notification will appear onscreen to inform the player of the reason why they currently cannot attend class.
  • Updated the layout of the infirmary; it needed more beds, because now it’s possible for numerous students to be resting in the infirmary simultaneously.
  • Students now turn and look towards Yandere-chan if they hear her footsteps during Low School Atmosphere.
  • Changed Kyuji/Toga’s reaction to a camera being aimed at their face.
  • Added new idle/walk animations for Toga.
  • Added 1 new hairstyle for Yandere-chan.
  • Added 1 new track to Mission Mode.
  • With the Easter Egg menu open, press the F1 key to enable rain. Open the easter egg menu a second time and press F1 again to put a raincoat on Yandere-chan. This is purely for fun, and is not intended to become an aspect of gameplay.
  • On a completely unrelated note, you can open the Easter Egg menu and press F2 to see an experiment that was inspired by the work of LuigiSake!
2/2/2019

  • The school’s sliding gate now makes sound effects as it opens / closes.
  • Adjusted Gaming Club lunchtime seating positions.

2/3/2019
  • Added a sound effect when loosening a pipe with a wrench.
2/15/2019
  • The player can now frame anyone for murder, not just Kokona during her cooking event. The process is described below:
  • Obtain a roll of masking tape in the Art Club.
  • Find a cardboard box in the Incinerator area, and use the masking tape to tape the cardboard box shut.
  • Wear gloves to avoid getting your fingerprints onto a murder weapon.
  • Stab a box cutter into the taped cardboard box.
  • Present the stabbed box to a student and ask for help getting the box cutter out. The student will agree, and put their fingerprints onto the box cutter.
  • Yandere-chan can now leave a note in anyone’s locker, not just Kokona’s locker. This means she can direct anyone to the school rooftop, a fountain where they can be drowned, or an area where an object can be dropped on their head. The process is described below:
  • Find a piece of paper pinned to one of the columns in the locker area, and interact with it.
  • A screen will appear, displaying all of the students that Yandere-chan has information on. Select a student, an arrow will appear above that student’s locker. This allows you to leave a note at that student’s locker.
  • In order for a student to take a note seriously, the note must relate to that student’s interests. (The student’s Persona is the biggest clue.)
  • Student lockers have been re-designed, but the “interact with lockers” animations have not been updated yet. The animations will, hopefully, be updated in the near future.
  • The “bucket of water above door” trap can now be used on any student, not just Kokona. As a result, now any student can now be drenched in liquid – water, blood, or gasoline.
  • If you would like to ignite a student who has been doused in gasoline, you now have another option besides flicking a match at them; you can now obtain a candle and place it on the ground. If a student steps on a candle while doused in gasoline, they will burst into flames!
  • If a student is doused with liquid, they become paranoid and become wary of traps. If you try to make a paranoid student pass through a door that has a bucket of water above it, they will dodge out of the way of the bucket when it falls. As a result, you cannot douse a student with liquid twice in one day.
  • Yandere-chan can no longer trip while carrying a bucket.
  • Many people suggested that the player could learn about gameplay mechanics from watching anime or reading manga inside of Yandere-chan’s room. It sounds like a fun idea, so I’ve decided to test it out; you can now find a new feature in Yandere-chan’s room. What you can currently find in-game is a rough prototype of the concept, and it will most likely be improved upon in the future.
  • All students’ Cleaning Time routines have been re-designed; there are no longer any bugs where a male student cleans toilets in the girls’ bathroom, or bugs where a character spins in circles at the school gate during cleaning time.
  • I recently had an epiphany regarding something that could potentially improve the framerate a lot. Please tell me if you see a noticeable difference in the framerate between the previous build and this new build!
  • I’ve updated the 3D models for the glasses that the player can put on Senpai at the Senpai Customization screen.
  • If you open the debug menu and press the F8 key, you can…”censor”…all of the blood in the game.
  • Added a new weapon to the game, found in the Light Music Club room. The current SFX are temporary.
2/16/2019
  • It is now possible to dump a bucket of liquid or weights off the school roof onto a student who is standing directly behind the school.
  • If anyone witnesses you touch a gasoline-doused student with a candle, they will recognize that you are committing murder and react according to their Persona.
  • Expanded the size of the candle flame’s collider so that it’s less likely for a gasoline-doused student to slip right past it without catching on fire.
  • Made adjustments to Yandere-chan’s character collider in an attempt to reduce chances of Yandere-chan getting stuck while walking up stairs.
  • From now on, if Yandere-chan gets too close to a student who is on fire, she will back away in pain.
  • Bullies will now react positively to a note in their locker mentioning “juicy gossip”.
    • A student who is soaking wet will no longer shove Yandere-chan.
    • Fixed typos in the End-of-Day Results sequence.
2/17/2019
  • Changed the Occult Club’s daily routine. Now, instead of spending all day inside of their clubroom, they walk around school and attempt to research “The Seven Mysteries of Akademi High” – a series of urban legends that are associated with the school. Currently, you can only see them research 5 of the 7 mysteries.
  • Added some new props to the school – a painting, some mirrors, a basketball, a piano, and an anatomical figure. These are connected to “The Seven Mysteries”. The 7 mysteries will play a larger role during Oka Ruto’s week at school.
  • Adjusted pathfinding grid so that students might be more likely to walk down the center of a hallway instead of sticking to the walls.
  • Male Sports Club members’ bodies now have varying degrees of musculature (thanks to help from EpicMealDev).
  • It is no longer possible to put a bloody box cutter into a cardboard box.
2/18/2019
  • Changed the Martial Arts Club’s daily routine; They now walk around school and practice martial arts in different locations. This increases the chance that they will become witnesses to your crimes.
  • Adjusted the hedges in the center plaza so that it’s no longer possible for Yandere-chan to become trapped between a closed door and a hedge.
  • Slight adjustment to the “leave a note in a student’s locker” feature; adjusting which subjects are interesting to which students.
  • Adjusted the two mirrors at the top of the northeast staircase so that they are no longer rendering the game’s skybox.
  • Added another Japanese garden to the school; this one is nearby the outdoor cafeteria area.
  • Made a tiny tweak to Akademi High’s exterior.
2/19/2019
  • When Yandere-chan dumps liquid or weights off the roof and presses the “Q” key (or “B” on Xbox controller), the player will see a little picture-in-picture camera view of the liquid/weights falling and hitting the ground (or its target).
  • Updated the Martial Arts Club’s hair colors and eye colors, since their old colors always bothered me a little.
  • Updated the texture for the painting in the Art Room (separate from the Art Club).
  • Fixed typo that caused headache poison to be labeled as “Emetic Poison”.
  • Lowered the file size of some textures that were too big.
2/20/2019
  • When using a candle to kill a student, witnesses will now acknowledge *which* student you were killing; this means that a student’s loved one will react to the murder by attempting to apprehend you.
  • From now on, students will refuse to help you take a box cutter out of a box if you’re splattered with blood while making the request.
  • From now on, the Student Council will evade bucket traps, since they are too perceptive to fall for such tricks.
  • From now on, when you destroy a weapon using the incinerator, it won’t re-appear at school on subsequent days.
  • It is now possible to drown a student who is cleaning a toilet bowl.
  • Fixed typos in student profiles.
3/2/2019
  • If a student finds a pool of blood, they will walk over to it and investigate it. After confirming that they have discovered blood, the student will run and tell a teacher. The student and teacher will run to the location where the blood was spotted. If the teacher doesn’t find blood (because the player has cleaned it up), she will assume she is being pranked, and return to the faculty room. If the teacher does find blood, she will call the police.
  • If any character witnesses Yandere-chan mopping up blood, they will realize that Yandere-chan is trying to cover up the evidence of a crime, and will react according to their persona.
  • If a student has lost a teacher’s trust, they won’t bother to reporting things to teachers anymore, and instead will go hide in a classroom where they feel safe.
  • If a second student finds blood while another student is already reporting the blood, the second student will go wait in class while the blood is being reported.
  • Everything stated above also applies to dismembered limbs and bloody weapons, as well.
  • If the player picks up an object that can be used as a weapon and drops it more than 10 meters away from its initial location, that object will be considered to be suspicious and dangerous, and students will react to it upon seeing it.
  • The first student to locate a suspicious/dangerous object will run and tell a teacher about it. Other students will simply ignore it and return to their daily routine.
  • If a teacher finds a suspicious/dangerous object (but doesn’t find any evidence of a crime) they will pick up the object and bring it to the faculty room.
  • A teacher’s fingerprints cannot be transferred onto a weapon. To make this more clear to the player, I will most likely adjust the “teacher picks up weapon” animation so that teachers use a handkerchief to pick up objects, instead of picking up objects with their bare hands.
  • Removed a debug command in Yandere-chan’s room that people were triggering accidentally.
  • Began to update the girls’ locker room with new models.
  • Updated the textures of the bullies’ phones so that their screens aren’t blank.
  • Updated shaders that weren’t being affected by changes in lighting.
  • Added 1 new hairstyle and 1 new accessory for Yandere-chan.
  • Updated Yamiko’s clothing in the Life Note cutscene.
  • Added voice-acting to the Life Note cutscene.
3/5/2019
  • Characters will now react to the sight of Yandere-chan carrying bloody clothing. The action is considered the same as carrying around evidence of murder (like a severed limb).
  • Removed the “students react to footsteps at low school atmosphere” feature, since it was changing the intended game design significantly and creating weird exploits. The feature may eventually be re-added if I can figure out a better implementation.
  • If there are bloodstains present at school when the police arrive (but no corpses) the text that displays during the End-of-Day sequence will reflect this.
  • If a student reports a severed limb to a teacher, the teacher will ignore less-important things (like dropped weapons) on the way to investigate the limb.
  • If a student reports a corpse to a teacher, the teacher will ignore less-important things (like dropped weapons) on the way to investigate the corpse.
  • If the police arrest someone, school atmosphere will go up, since the population of the school believes that the perpetrator has been caught.
  • If Yandere-chan picks up a weapon while a teacher is walking over to investigate that weapon, Yandere-chan will get in trouble.
  • Removed the matchbox from Info-chan’s Drops menu, since the mechanics for setting someone on fire no longer involve matches.
  • Characters will now react to the sight of bloody clothing on the ground, and will report bloody clothing to teachers.
  • Yandere-chan will now wear a towel over her body when she takes off her clothing in the girls’ locker room.
  • Reduced the amount of time that students are willing to pose for a photograph in Mission Mode, to nerf an exploit that allowed the player to separate a student from other students by aiming a camera at them for a long time.
  • Changed the font used for the Mission Mode menu, because it had unintended side-effects when the game was running with 1/8 textures.
  • When a corpse is discovered in Mission Mode, the game will now display the name of the character who discovered the corpse.
3/15/2019
  • Some weapons look suspicious and dangerous (like the Occult Club’s knife) and other weapons look like harmless everyday objects (like scissors or a screwdriver). If a student finds a dangerous-looking weapon, they will report it to a teacher. However, if a student finds a harmless-looking weapon, they will pick it up with their bare hands and put it back where it belongs.
  • Students who are leading teachers to suspicious objects (or teachers who are following students to suspicious objects) will no longer be affected by liquid coming out of bucket traps. It would simply create too many new scenarios.
  • Students will no longer react to bloody uniforms as if they are witnessing murder (but teachers will still assume that Yandere-chan has committed a crime if they see her carrying around a bloody uniform).
  • Selecting the music note in the pause screen menu will now display an “Audio Settings” menu where the player can adjust the game’s background music, or turn it off.
  • From now on, if Yandere-chan tries to take a weapon out of the faculty room’s storage box while teachers can see her, she will instantly get in trouble for it.
  • Fixed a problem with the teacher’s “calling the cops” animation that would cause her arm to twitch while making the phone call.
  • From now on, students who are told to “Go Away” will go to the hedge maze, rather than the school roof.
  • Teachers will now use a handkerchief when picking up a weapon that has been dropped on the ground.
3/17/2019
  • The player can now find an ID card in the faculty room. If Yandere-chan carries this ID card with her while walking through a metal detector, the detector will ignore her.
  • Changed the criteria that will make a student willing/unwilling to pick up an object. Students will now pick up most objects (as long as the object isn’t obviously dangerous).
  • Students will no longer put misplaced objects back in their proper place if the student hasn’t even put their shoes on yet.
  • A student who is carrying food will no longer pick up misplaced objects if they are in the process of handing out food.
  • Students will now refuse to pick up misplaced objects if they are on their way to class.
  • Added a new easter egg to the game! If you open the Easter Egg Menu, you’ll see a new addition. If an easter egg isn’t listed in the Easter Egg Menu, this means that it doesn’t have any functionality yet.
3/31/2019
  • Increased speed of Enigma Mode attack animations and also allowed the player to cancel the animations by inputting movement. Attacking in this Mode should now feel faster, more fluid, and more satisfying.
  • Male characters now have male voiced lines when reacting to a note in their locker / being pushed off the roof / being splashed with liquid.
  • Updated the “exchanging shoes at locker” animations so that students are no longer interacting with invisible doors.
  • Updated the “finding note in locker” animations so that students are no longer interacting with invisible doors.
  • Students will now refuse to pick up metal objects if metal detectors are present at school.
  • Added new sound effects for the guitar weapon.
4/1/2019
  • Evolved Yandere Simultator to its permanent final form.
  • Reduced the femininity of the game by 100%.
  • Increased the masculinity of the game by 1000%.
4/2/2019
  • Yaku’s visor will now do a better job of reflecting his emotions (sad eyes if he lost the trust of a teacher, angry eyes if he holds a grudge against Yandere-chan, pained eyes if he eats poisoned food, etc).
  • From now on, a student who has been told to distract a bully will give up if they witness the bully bullying someone.
  • Cooking Club members will no longer attempt to feed characters who are already eating a snack.
  • “Man Mode” is now accessible from the Easter Egg menu.
4/12/2019
  • Added a new type of mission to Mission Mode – “Multi Mission”. This allows the player to play a mission with up to 10 different targets. You can also select the exact method for killing them. I might expand on this mode in the future, depending on whether or not anyone is interested in it.
  • Added a debug command to the debug menu that will obscure the screen whenever an attack animation is playing.
  • The Student Council will now send you to the guidance counselor when they catch you doing something that a teacher would yell at you for. (But will still pepper spray you if they think that their life is in danger.)
  • Removed Kokona’s lunchtime event, since that event only existed so that the player could test the bento-poisoning mechanic, and the bento-poisoning feature is now available for all students.
  • From now on, when a student sees a suspicious object, they will only react to it once, instead of continuously reacting to it until it leaves their field of vision.
  • From now on, after successfully pick-pocketing a character, a little notification will appear at the top of the screen to inform the player that they have succeeded.
  • Added voice lines for the new dialogue that was given to teachers in recent updates (reacting to blood pools, bloody weapons, dismembered limbs, etc).
  • It is now possible to push a student off the rooftop while they are dusting off erasers near the rooftop railing.
  • Adjusted “Kill All” debug command so that it can kill student council members in addition to normal students.
  • Added tutorial pop-ups. The pop-ups can be disabled with a single button push, if they’re annoying.
  • Female students now wear towels in the locker room instead of stripping completely naked.
  • Added a new easter egg to the Easter Egg Menu.
4/18/2019
  • When Yandere-chan stands in front of a door, a little pop-up appears at the bottom right corner of the screen, telling the player the name of the room they’re trying to enter (such as “Announcement Room”). Due to a bug, this pop-up was sometimes displaying the name of a room *above* the current room. This bug has been fixed.
  • Pressing the Debug Key during Mission Mode will now open up a small debug menu that allows the user to choose whether or not they would like to censor panties/blood/weapon-based killing animations.
  • When pushing the Q Key (or the B button on gamepad) while pushing someone off the roof, you will now see a picture-in-picture view of that person hitting the ground.
  • If you speak to a student after putting a note in their locker, you can now see a button prompt that will cause the student to go check their locker for the note.
  • Added a map to the game! Press spacebar (or “Back” on the Xbox Controller – where “Select” would be on a PS2 controller) to open it
  • Tutorial pop-ups can no longer appear while the Cinematic Camera is active (this could create the impression that the game had frozen).
  • During a Multi Mission, the pause screen will now communicate which students are dead and which ones are still alive.
  • Added a short animation that will play whenever Yandere-chan equips or de-equips a weapon.
  • Yandere-chan will no longer be bald when aiming her camera in Cinematic Camera Mode.
  • Tutorial pop-ups are now automatically disabled in Mission Mode.
  • Added 5 more tutorial pop-ups to the game, for a total of 15.
4/24/2019
  • If a student takes photograph of Yandere-chan committing a crime with their smartphone, and is subsequently killed by Yandere-chan, the police can still discover that Yandere-chan is a criminal by checking the student’s dropped smartphone and finding the incriminating photo. To prevent this, the player is now required to destroy the dropped smartphones of anyone who has taken a picture of Yandere-chan committing a crime. (There is no animation for it yet, but you can still break phones).
  • Senpai has a strong sense of justice, and has disdain for people who commit evil behind a veil of anonymity. The sight of a masked murderer would fill Senpai with disgust and cause him to disregard his own safety and unmask the murderer at all costs. This means that if Senpai sees Yandere-chan commit murder while wearing a mask, he’ll run up and rip the mask off her face, which will cause an instant game over.
  • From now on, it is only possible to put a mask on, or take a mask off, if no student can currently see you.
  • The Occult Club’s leader will now spend time in the Occult Club from 5:00 PM onwards, since otherwise, it’s difficult for the player to attend the Occult Club’s daily club activity.
  • Yandere-chan can now perform a kidnapping if she has a sedative purchased from Info-chan, instead of being limited to using a tranquilizer stolen from the infirmary.
  • During the Occult Club’s club activity sequence, the number of characters in black robes will now reflect the current number of living Occult Club members.
  • When viewing the map, you will now see some text informing you of what floor you are currently viewing (bottom floor, rooftop, etc).
  • If any of the bullies are dead, then the player can’t request a task from Gema, since his task would have involved the bullies.
  • If the player tries to ask a bully to distract Gema, the bully will refuse, unless Gema’s task has been completed.
  • If the player attempts to lead a student into the Headmaster’s office, the student will refuse to go inside.
  • Added props to the inside of Info-chan’s “Info Club” room.
  • Changed the appearance of the tutorial windows to make the text more legible.
  • Moved Kokona’s bag so that it’s actually at Kokona’s desk.
  • Rebalanced the difficulty of the struggle minigame.
  • A few years ago, a certain dude made a request. I have finally granted it. To see it, walk into the school infirmary, face the nurse, and type a certain phrase using your keyboard. It’s 8 letters long.
  • If a teacher witnessed a mind-broken slave commit suicide, and then witnessed Yandere-chan do something suspicious/dangerous, she accused Yandere-chan of murder, but makes more sense for the teacher to assume that you must have *something to do with the murder*, so her dialogue has been adjusted accordingly (but no voiced line yet).
4/25/2019
  • Yandere-chan is no longer allowed to run away while being chased by a Teacher/Hero/Senpai; it created too many exploits and holes in the game design. Instead, if a character is running at Yandere-chan, she will stare down her pursuer and face them head-on.
  • The act of crouch-walking or crawling around on the ground will now be considered suspicious, and will result in the same reaction as maniacal laughter or low sanity.
  • If students see you covered in blood and carrying a weapon while School Atmosphere is low, they will automatically assume that you’re a murderer and react accordingly.
  • Made a slight adjustment to the static that appears when the player tries to make Yandere-chan leave school before Senpai leaves.
  • Updated the appearance of Yandere-chan’s Sailor Moon-inspired hair model.
4/27/2019
  • Added “Discord Rich Presence” to the game, thanks to assistance from PiranchDev! This means that, if you play Yandere Simulator while logged into Discord, your Discord status will update to “Playing Yandere Simulator” – with additional text describing exactly what you’re currently doing in-game!
  • After witnessing murder, Social Butterflies will now run to the largest group of students at school, instead of always running to the plaza.
  • From now on, you will see a “Red String of Fate” connecting Senpai to the current rival when Yandere Vision is active. Because there is no rival in the game right now, you will see the Red String connecting Senpai to the “Indestructible Rival” in the school plaza.
  • Added short fences in the Japanese gardens to prevent the player from being able to walk on top of water.
  • Yandere-chan is now allowed to equip a weapon while a pursuer is charging towards her to apprehend her.
  • Students will no longer be willing to follow Yandere-chan if they are currently wearing a swimsuit.
  • Added one new hairstyle for Yandere-chan.
4/30/2019
  • When Yandere-chan’s sanity is very low (less than 33.33%)…
  • …she will begin to have “intrusive thoughts” – no matter how hard she tries to concentrate, she will be unable to stop thinking about killing her rival. From the player’s perspective, these thoughts will be perceived as ghostly visions of Yandere-chan performing gruesome murder animations on Osana.
  • …she will lose the ability to distinguish people from one another. Because the only person she cares about is her Senpai, everyone else will start to look like a dark blur. Her fellow students will lose all color, and will to appear as black silhouettes.
  • …smudges will appear around the edges of the screen.
  • …she will become unable to resist her murderous urges, and will automatically attack anyone who is within range.
  • …the game’s visuals will become more desaturated.
  • Yandere-chan’s current level of sanity will now be represented by a semitransparent number visible over the cardiograph at the bottom-right corner of the screen.
  • Crouch-walking or crawling in front of Senpai will no longer result in an instant game over, and instead just creep him out.
5/2/2019
  • Adjusted the pose that Yandere-chan enters as her sanity deteriorates so that it's less stiff
  • Minor aesthetic changes to various characters (like changing the color of Midori’s socks to make them match her hair).
  • The player is no longer allowed to place a bucket trap on the Headmaster’s door, because it could lead to several bugs.
  • Adjusted the expression that appears on Yandere-chan’s face as her sanity deteriorates.
  • Replaced Horuda’s hair model with a superior one with no bald spot.
  • Added one new hairstyle for Yandere-chan.
  • Added a new easter egg
5/6/2019
  • Because Yandere-chan now wears a towel inside of the locker room, the “Nude” button prompt has been updated to say “Towel” instead.
  • Added one new hairstyle for Yandere-chan.
5/15/2019
  • Restored “Look at a picture of Senpai to restore Sanity” feature.
  • The “Censor Attack Animations” command now works with the attack animation that occurs at the end of the Struggle minigame.
  • Fixed exploit that allowed the player to attack the Student Council during times when they shouldn’t be vulnerable.
  • Teachers and the nurse no longer use the “default” face and have slightly different faces than students.
  • When using a picture of Senpai to restore Sanity, the player will hear Yandere-chan release a happy sigh.
  • Yandere-chan’s involuntary giggles are now different from her intentional giggles.
  • Tweaked the appearance of the skybox slightly.
  • Updated “broken smartphone” model.
5/17/2019
  • Made very minor aesthetic changes to some characters; for example, teaches no longer have blue eyelashes.
  • Bullies will no longer have the incorrect skin color when they are wearing a towel or a gym uniform.
  • Bullies will no longer wear their accessories when wearing a towel inside the locker room.
6/1/2019
  • From now on, the End-of-Day sequence will include a new segment: eyewitnesses who saw Yandere-chan commit murder will report her to the police. If at least 5 students accuse Yandere-chan of murder, she will be arrested. If less than 5 students accuse her, the police will not have enough justification to arrest her. (Cowardly students will not report the player to the police.)
  • Accessories that were programmed to change color when the player pressed the spacebar will now change color when the player presses the Left Alt key instead.
  • Fixed baseball bat animations that would cause students to pop up into the air and flail around after being killed.
  • Attempted to fix exploit that would allow the player to kill Nemesis from extreme distances.
  • Minor aesthetic changes (some male characters were using female face textures).
  • Added cool post-processing effects to the Mission Mode menu.
  • Added one new hairstyle for Yandere-chan.
  • Added a new easter egg.
6/2/2019
  • Delinquents and Spiteful students will no longer offer eyewitness reports to the police.
6/15/2019
  • The player now has a “Cyberstalk” option at their PC at night-time. You can cyber-stalk a student to instantly learn all of their likes/dislikes. To view them, go to their profile and press the R key (or the Y button on controller) to see a grid depicting all of their interests. This is intended to be used as a “cheat sheet” to make the match-making feature easier. It will also be helpful if I eventually re-design the conversation system so that, to gain favor from a student, you need to say positive things about what they like, and say negative things about what they dislike, in order to gain favor with them.
  • Finally implemented an intro animation for the game. Senpai’s appearance and the school uniforms are dependent on the player's choices in the Senpai Creation screen.
  • When starting a new game, the player will now see a “Message from the Developer” screen after Yandere-chan’s conversation with Info-chan. The purpose of this screen is to clarify something that confuses a lot of newcomers.
  • Thanks to advice from a friendly Unity developer, you should now notice improvements to the game’s framerate when looking towards the front of the school at the beginning of the day.
  • Updated the Falcon Mode textures and models so that the character is a parody, rather than an exact replica of a per-existing character.
  • Updated the Berserk easter egg music with an original track instead of a royalty-free track from the Internet.
  • Yandere-chan will now scoot close to a bento when poisoning it, instead of poisoning it from a meter away.
  • Students will no longer accuse Ayano of murder if Ayano was wearing a mask at the time of the murder.
  • Updated some face textures (some male students were using female face textures).
  • Added an animation that will play when Yandere-chan crushes a smartphone.
  • Updated the Debunk page with 5 new debunks at the bottom of the list.
7/1/2019
  • While implementing some of the events that occur between Osana and the “Mysterious Obstacle”, I discovered that there simply wasn’t enough time in the day for all of Osana’s events to take place. To provide Osana with a longer span of time for her events to take place in, I’ve slowed down the game’s clock; the span of a minute in Yandere Simulator is now approximately 1.5x longer than it was before.
  • Updated some characters’ likes and dislikes to be more consistent with what I’ve said about them in the past.
  • Re-balanced the price of purchasing a sedative from Info-chan.
  • Replaced music that plays during Shipgirl easter egg.
7/3/2019
  • Fixed problem with Ryuto’s hair texture that made a weird seam appear at the back of his head.
  • Removed a column which was placed in a hallway as a test.
  • Restored a character who had been disabled.
7/18/2019
  • The “Bullying” topic has been restored to the list of topics that the player can write about when leaving a note in a locker.
  • Fixed bug that caused female Titans to spawn with towels and male Titans to spawn without face textures.
  • Minor cosmetic changes to some characters’ face textures.
  • Updated portraits for all characters.
  • Re-positioned some of the props in the Science Club, and added one new prop to the Science Club.
  • The radio will now emit music notes when music is playing.
8/1/2019
  • Yandere-chan can now access a part-time job from her room – working at a maid cafe!
  • Yandere-chan can use the maid minigame to earn money. The player’s current amount of money will be displayed at the top-right corner of the game, beneath the clock.
  • It is now possible to use Yandere-chan’s home computer to access an online store. Currently, only one item is sold through this store, but more items will become available in the future.
  • From now on, you will have to pay $1.00 to obtain a drink or a snack from the the vending machines at school.
  • In the version of the game that contains Osana, debug commands (such as “instantly befriend all students”) will not be available. Thus, when I put Osana into the game, it must be possible to befriend all students through normal gameplay, without use of debug commands. In order to befriend a student, the player must do a “Task” for them. However, implementing a “Task” for every student would be extremely time-consuming, and would delay Osana. So, instead of implementing a unique Task for every student, I have decided to implement one generic Task that applies to every student in the game. In the final game, all students will have a unique Task, but for now, most students will simply use this generic placeholder Task.
  • Members of the Cooking Club will no longer attempt to give food to any student who is currently waiting to meet someone else as a result of a note in their locker.
  • One of Yandere Simulator’s old post-processing effects, “Ambient Occlusion”, has been re-enabled. If you dislike it, you can disable it from the Settings menu.
  • Until now, the shower buildings were using placeholder exteriors. As of now, the shower buildings have finally been updated with better exteriors.
  • Removed the white cube that was floating in the Light Music Club.
  • Fixed props in Science Club that were floating in midair.
8/2/2019
  • The player is no longer able to receive a Placeholder Task from a delinquent or Gema.
  • The text “(PLACEHOLDER TASK – WILL BE REPLACED AFTER DEMO)” will now appear during a Placeholder Task.
  • Minor changes to the UI of the online store.
  • Minor fixes to paintings in the Art Club.
  • Updated sponsors screen.
8/3/2019
  • It is no longer possible to collide with the cardboard box in the meme closet, because it could be exploited in various ways.
  • The Science Club’s blood-cleaning robot now moves 4x faster and can travel up stairs.
8/15/2019
  • Each of the delinquents now has a task; this means that it is now possible to befriend all of the delinquents.
  • Normal students will do favors for you after you befriend them. However, delinquents function differently; they won’t do favors for you, even if you befriend them. Instead, befriending a delinquent offers different benefits.
  • If you befriend a delinquent, they will no longer shove you when you get close, or become alarmed when they see you with a weapon. However, the true benefit of befriending the delinquents is something else entirely:
  • If you befriend all delinquents, dye your hair blonde, lower your reputation below -33%, and use the “Tough” persona, you will be able to speak to Umeji (the delinquent in the yellow shirt) about joining their gang.
  • If you join the delinquents, your reputation will never be able to rise higher than -33%, but you will gain a new command, “Intimidate”, which forces students to do favors for you without needing to befriend them first.
  • It is now possible to purchase blonde hair dye from the online store accessed in your home.
  • When wearing a delinquent mask, press the Left Alt key to change the texture on the mask.
  • Replaced the “teacher counters attack” animation with a new one. The original animation was weird, it looked like something an anime villain would do.
  • Balanced maid minigame payouts so that it’s possible to achieve $100 on easy mode with perfect gameplay, and $200 on hard mode with perfect gameplay.
  • Updated music, credits, and menu background artwork for maid minigame.
  • Added one new hairstyle for Yandere-chan.
  • Added a new easter egg to the game. When you activate this easter egg, there will be new functionality on the X button, Y button, and RB button. (On keyboard, it’s the F key, R key, and left ctrl key.)
  • Updated the “Berserker Mode” easter egg. The Drakeslayer weapon now has unique attack animations when pressing the X or Y buttons (F key or R key).

  • Changed the drama club’s silk gloves from white to black, because it looks cooler and matches Yandere-chan’s color scheme.
  • Fixed the glitchy physics of Yandere-chan’s latest hairstyle.
8/22/2019
  • Removed exploit that allowed players to keep a character stationary indefinitely by talking to a student about their Task and never dismissing the Task Window.
  • Adjusted the pathfinding grid so that it should be less likely for a student’s path to the male locker room to be blocked.
  • Added voice lines for the “Generic Placeholder” task. (Female only.)
  • Turned down the volume of the delinquent leader’s voiced lines, since they were distorted.
  • Changed the animation that Yandere-chan performs when she uses the Intimidate option.
  • Finally finished implementing the “Tasks” screen accessed from the pause menu.
  • Adjusted subtitles for students reacting to certain types of weapons.
  • Added a new easter egg – “Witch Mode”. Press RB (left ctrl) to activate her power, and then press X (the F key) to activate her secondary power.
8/25/2019
  • Moved the delinquents to different classrooms (they are 2nd-years and 3rd-years, so they can’t occupy 1st-year classrooms). Horuda and Kuu Dere have been moved to 1st-year classrooms.
  • If Yandere-chan talks to a student while standing extremely close to them, she will now back up to a more reasonable distance.
  • The “Learned Topic” and “Learned Opinion” messages will now specify exactly what topic/opinion was learned.
  • The text on the welcome mat in front of the boys’ locker room is no longer reversed.
  • Doors will no longer shove Yandere-chan when they are opening/closing.
  • Added sound effects and voices to the maid minigame.
9/1/2019
  • In a student’s profile, you can see a list of their likes/dislikes. Most social butterflies dislike the topic of “Gossip”, but were responding positively if the player left a note in their locker about the subject of “Juicy Gossip”. To fix this contradiction, I have removed the “Juicy Gossip” option and replaced it with something else that social butterflies would respond positively to.
  • Students will now become suspicious of you at 2x the speed that they previously would.
  • Teachers will no longer scold you for being late to class if they are not present in the classroom.
  • Restored “Near Mode” to the easter egg menu after accidentally removing it in the last build.
  • Prevented Osana/Raibaru’s hair from being accessed through Pose Mode.
  • Used one of Unity’s compression options to lower the file size of the build. This is a test-drive to see if it negatively impacts the build.
9/15/2019
  • It is no longer possible to commit murder if there is no spare clothing available at school (it would lead to a situation where the player is stuck in a towel in the locker room and has no way of obtaining any more clean clothing). There is a tutorial pop-up explaining this if the player attempts to attack someone without any spare clothing at school.
  • People reported that the game was crashing when they attempted to load into the school environment. This may have been due to the new compression I was testing out, so I’ve disabled it.
  • Added a wooden platform behind the legendary cherry tree. (This is to allow a place for potential witnesses to stand.)
  • Re-designed some aspects of the the plaza area. (This is to facilitate that option of stealth gameplay during Osana’s week.)
  • Replaced Musume Ronshaku’s old task with a new one (her old task was too similar to one of the delinquent tasks).
  • Adjusted student likes/dislikes (Every student needs at least 5 likes and 5 dislikes for gameplay purposes).
  • Added a little visual effect that appears when Yandere-chan giggles.
  • Added one new hairstyle for Yandere-chan.
  • Updated two student portraits.
9/16/2019
  • The game will now remember your preferences when resetting the day / resetting the week.
  • It’s no longer possible to speak to a student who is investigating a weapon/blood pool/limb on the ground.
  • Cooking Club students should no longer attempt to give food to a student who has walked out of school.
  • The “Invert Y Axis” setting will now also invert the Y axis when aiming the camera in first-person mode.
  • Updated teachers’ clothing textures and adjusted their models slightly.
  • For gameplay reasons, expanded the size of students’ vision cones.
  • Updated the text in Horuda Puresu’s profile.
9/18/2019
  • Students with unique walk animations where they put their hands near their faces (like Beruma and Toga) will no longer use those animations while carrying cleaning items (because the cleaning items would clip into their faces).
  • Yandere-chan will no longer be considered suspicious when carrying a guitar if she is in the Light Music club.
  • Students now have reactions to seeing Yandere-chan carry a fire extinguisher, pipe wrench, or guitar.
  • Fixed a prop that was floating in midair in the Photography Club.
9/21/2019
  • Using the debug turtle to clean clothing will no longer result in a scenario where the game believes that there is no clean clothing present at school.
  • Added teeth to Yandere-chan’s smile on the title screen.
  • Reduced the volume of the woodchipper and radio.
  • Yandere-chan now has a different line for complimenting male students.
  • Fixed some inaccurate subtitles for certain students’ Tasks.
  • Added warning message to the debug turtle menu.
  • Added a new easter egg.
