The controls for turning are very difficult, especially when you lag and you get stuck spinning in circles. Otherwise I think it's pretty good, it's not often you see a first person shooter flash game.
Could possibly use a pause during the levels, but it's not necessary since the levels are quite short and easily restarted. Mute button maybe? But those are minor. I like the concept a lot :)
Its decent, but the jumping and movement don't quite feel natural, and you can get up on ledges even if your jump height isn't high enough just by moving next to them.
Very little action what there is is easy, seems like mostly cinematic. Well done but the game isn't even nearly long enough to warrant going to another site to get a save file.
I seemed to encounter a glitch where I paused the game, it had the sign up and it was fuzzy, but the game was still running, then I hit p again and the game stopped, but it became unfuzzy and the sign left.
Colors are a bit too similar at times but otherwise good. I also had an issue when I walked away for a few minutes during a game and when I came back was unable to play, had to refresh.
