For some reason I can't leave a rating? It's a cute game, I think with some fail conditions (like damaging too many civilian vehicles or letting too many racers escape) and some good sound design you could make something cool. :D

That's a good start! Graphics are nice, and the concept of having to hit only specific ships brings interesting mechanics.

On the technical side, there's a little bug: if you go forward/backward and sideways at the same time, the forward/backward movement won't stop until you stop moving sideways.
