Mad props.
Good sir, I have to give you mad props for creating a 3D game with flash. Everything works, but it's difficult to get it all to work... in the player's favor, I suppose. If you could include some sort of compatibility with external controllers (a PS3/360 controller) then this game would really, really deserve a 10. The game's frustrating, but I was never good at FPS games.
Despite anything else, your programming skills are amazing!
