I can understand that the game is made with comedy (like the menu or the T pose) but I think that if it were at night and there were ambient sounds it would improve even more. Good game by the way :p
This game is very cool and I loved the final part but it is a bit annoying that you cannot skip the dialogues because when you have passed 2 levels and you start from the beginning you have to see them again and it takes a long time.
This game have creepy moments like the maze without exit or the detail of see the killer from the window, but maybe you should put some animations for this killer.
