Maybe Yanderedev'd put a little too much effort into the test rival Kokona, but in 2016 the game was pretty much centered around her. With almost all elimination methods available by December, she was as close as possible to a real working rival, making the game more like a sneak peak of the final game. The only thing missing was the ending cutscene (a few lines of it can be located in the game data files).

However it's still called "debug build", which means that eventually progress will cause things to break. By the end of 2016 it was pretty obvious that it's pointless to keep adding features focused around someone who isn't even supposed to be a real rival, so right now the focus of the game shifts towards Osana more and more with every update. For instance Senpai's routine has been modified so he eats lunch on the rooftop with Osana, which makes Kokona's wednesday event pointless because she talks about Senpai when he's not even there...

The point is - the debug builds from now on until Osana is fully implemented will probably be... well, debug builds. They will probably only make sense if you "get past the defenses" and add Osana but other than that - they intend for you so report bugs, not for actually playing, in which case you should probably stick with the December builds.
