Bad Time Mode



Bad Time Mode is an Easter Egg Mode in Yandere Simulator.

Appearance
This mode is a reference to the video game Undertale. Press U to activate the mode. It cannot be deactivated until the game is reset or the day ends. Yandere-chan will resemble the character Sans from said game. She will have light grey skin with black eye sockets. She will be bald, and when any special attacks are used, her left eye will glow blue. The player will not wear the school uniform, but a blue jacket and black pants with white stripes. When idle, she will place her hands in her sweatshirt pocket and sway side to side.

A song, the theme of Monty on the Run, will play the entire time. This music will eventually be replaced as to not be copyrighted.

Attacks
During this mode, the player can use several attacks that Sans uses during the Genocide Route to kill students, teachers, and Senpai.

Gaster Blaster
If the player presses Left Control, a large, six eyed skull called a Gaster Blaster will appear and shoot a white ray that will kill anything in its way. Pressing Left Control a second time will make two Gaster Blasters appear, pressing it a third time will make three Gaster Blasters appear, and so on when pressing it a fifth time resets the amount. The player can use the Blasters to kill Senpai.

Psychokinesis
It is impossible to interact with any student in this mode as the button for Psychokinesis replaces the talk or attack button. Once close enough to a student or teacher, the player can pick up them and throw them around. Students who witness the floating corpse will treat it as a random corpse, so no Heroic or Strict teachers will come to attack the player. Since Senpai has his pink aura surrounding him, it is not possible to use psychokinesis on him.

After a student dies due to Psychokinesis, it is not possible to use it again on the corpse.

Bone Attack
If the player holds down Left Control, many bones will rise from the ground within a short range. Any student or teacher that comes within contact with a bone will die instantly. The bones will appear through any prop, including walls. This bone attack can be used to kill Senpai.

Bugs

 * The player's textures will glitch if she wears gloves. If the player takes off the gloves, then Yandere-chan will wear the normal school uniform.
 * Yandere-chan will lose her skin texture if she goes nude in the Shower Room. If she puts on a uniform, she will revert back to Yandere-chan, but with her powers still activated.
 * If Yandere-chan uses the bone attack while Kokona is eating on Wednesday, she will die. If the player picks up her body, she will continue her eating animation while Yandere-chan is carrying her.
 * If the player uses psychokinesis in front of the delinquents, they will run up and hit her with their weapons, but she will not become comatose. Once she drops the student, the delinquent will continue to follow her around without harming Yandere-chan.

 * All Undertale audio, Sans' battle song MEGALOVANIA, and the original Gaster Blasters were removed in the February 15th, 2016 Build.

 * If Senpai is killed in this mode, he will respawn the next day.
 * The player can press D to disable the copyrighted music.
 * This mode was implemented in the January 15th, 2016 Build.
