I really liked the atmosphere and the different rooms, but I could get very far due to the enemy/just getting disoriented.
My game had a similar concept (but 2D), so it was interesting to see a 3D horror take on the idea.
I maybe found a small bug? Sometimes I couldn't continue to rotate the camera with the mouse, like I had reached the bounds of the screen. This was in full screen on firefox, if that helps.
