First time I am hearing about this. What version? Give more details please.
im using the 0.3.4.01v of the game on windows . and to better describe what i mean by "glitches out" is that sometimes some parts of the background would disappear or looks like some kind of z fighting. varying on how bad it is. sometimes not even that noticeable, to having almost no background. and from what ive seen mainly affect thing in game windows (like on the bus and in the school) and some walls.
i have used some of the in game cheats but have not altered any of the game flies, apart from deleting some saves . lastly recently i have deleted all my save from the games files and it has seemed to have fixed it (or at least for now) and thank you for time and making a very fun game.
