Great, the scares should start a bit later, i think the first one with the chair is too extreme, when you are just coming into the Game.
I think i enjoyed the ones in the third night the most, where you only see glimpses of something moving, those were great! I also liked the progression, that the Player tries to have less lights active at a time.
And scale down the size of the Game a bit, maybe it's the Textures but it doesn't have to be 1 GB for such a small Level. Good Job!
