Very entertaining.
That was pretty good. I don't really like the Capture the Flag part, though. And to answer Legovski, just shoot everything that the Instructions page tells you to kill (Remember: the red factories, not the brown ones.)
The controls were VERY difficult to work with. You should make the steering commands the same for both directions: if "up" makes you go up when facing right, why does "up" make you go down when facing left? Other than that, it was pretty interesting to see what some people can make. It needs sound, though.
