I never realised how rubbish I was at "Space Invaders"-style games until now . I think I'll stick to other game genres.

The game ran smooth on my work PC here, which is ultra crappy. I liked what I saw. The next task for you could be to add some menus/options/what have you plus a little bit of eye candy.

Plus some big-ass laser beams that can destroy planets. I like those.
