First half of the game was great. Second half is not nearly as good. Issues I noticed:
Crashed 3x going through doors
There's no collision on the wall to the right of the cafeteria door
Music in the devroom keeps cutting out (other audio does not)
Multiple puzzles on the second half are confusing and hard to parse (went to pikasprey's playthrough to look at those parts and he had problems at the same points)
No way to see what endings you're missing or how to get them
