Wasn't there also the thing where the source code Unity files leaked and people realized that he used this massive if/else if/else statement to check every student that was still alive by ID? And the worst part is that a later leak showed that he rewrote it as a more efficient switch statement to prove that he knew how to do it, but commented it out leaving the horribly inefficient if/else if/else statement method. 

For clarification, an if/else statement has to check each condition 1 by 1, while a switch will jump straight to the true case, iirc. For this reason, in a situation like in Yandere Simulator where it's checking every single npc, a switch is faster.

He literally showed it on his programming livestreams from what i remember. And yeah, iirc at one point it was running 30000 if else statements every frame or smth ludicrous like that. 

There are also far more issues than that and the aformentioned model issues. For example, whenever anyone calls him out on bad optimisation he tells them to stop playing the game on a shit laptop, yet exclusively plays it in 720p (the game also has a bunch of issues in 1080p because he doesnt give a fuck)

That and hes a creep too! Hes sold schoolgirl body pillows and advocated for a "teenage sex test/license". Disgusting guy...
