Shoot-em-up waves

The first computer game my father bought was "Apple Galaxian" - I had asked for Space Invaders, but the guy at the local computer store said that Galaxian was better. I think he was basically right, but I also think that he was doing a bit of a bait and switch.

The one thing that's most interesting about the difference between Galaxian and Space Invaders is the arcing attacks that the enemies follow.
