Just leaving objective feedback:
The swimming ghost doesn't move (seems to be stuck at doors). I didn't want to waste my talisman so I jumped and pressed e to open and enter the door, and my game suddenly froze with a black screen. I'm crouching but unable to move or cancel crouch. Also, sometimes when I peek into a door and release R, my screen doesn't come back to the place I was at but stays at the "peek" perspective.
Thats all the issues I found. This game is great, and I really see towards future developments!
