Galaxians

Ummm... This isn't Galaxians, it's Space Invaders with Galaxians-style graphics (except in Space Invaders, they would shift down when an invader reached the edge of the screen; here they do it after a pre-defined number of steps). Not a bad implementation, but I fail to see why you couldn't have added SOMEthing original.

This is already an arcade classic, the only different is that it has very annoying noises. 2/5, but only because I'm feeling nice today.
