Both loved and hated the camera angles. I dislike the turning controls. When the hallucination first appear it was actually creepy to look at. I feel the game could have benefited from some droning music or maybe just a looping buzzing sound from the ceiling lights to better set the mood; it felt very quiet (not in a particularly scary way). Also, when the monster chases you its really difficult with the camera angles to both escape it and figure out where to go.
Overall pretty cool game. Cool death animation btw.
