Not bad, I guess, but it gets old in a hurry. Thrusters handle nicely, but I think a slightly faster firing rate would be more fun. Very retro, which I'm sure is what you're going for, but I almost feel like the graphics could use a little tweaking. You can easily get away with it on Pong ('cuz honestly, whatta ya gonna do with Pong graphics?), but when spaceships are involved, it's nice to have a little more to look at. My own personal preference, of course.
