First, the game's atmosphere looks excellent, the lightning on the walls and on the primary character paint a pretty sci-fi horror, like Dead Space. The sounds for the gun, the enemy, and the doors opening are also fantastic. A few drawbacks, more nitpicks really, I felt were that the player didn't follow where I was facing - especially when I was somehow aiming behind the character; there weren't any directions on where to go so I sort of wandered around the main starting area for a bit, before I opened a door by accident; the music did stop after a way, and finally, the enemy still followed the character even after I had defeated him. As I said I consider these drawbacks more nitpicks and I think this is a very good prototype. Though one change I would consider is the aiming animation, as the character looks like he is gliding.
