I like it!
Really good atmosphere! My favorite room was the room with the bookshelves in the small hallway that leads to another key.
Some things that I would change tho, for example if you walk into a wall the camera goes through the wall and the AI for the killer wasn't hard to avoid at all most of time he is either stuck on a door, can't find me even though I'm right infront of him, and I could just easily walk around him.
Great job!
Also if you could I would really appreciate it if you could give some feedback on my game too :)
