It delivers a nice horror vibe, the monster design and the sound effects are pretty sweet. The camera movement felt nice and smooth, but I ran into some troubles at times trying to rotate and getting stuck at a certain point view.
Hmmm I think it is my bad, I played the browser version not in full size, so when the mouse went out of edges it obviusly wasn't responding, I'm noticing it right now. I downloaded the Windows version to check that out and it rotates perfectly.
