Pac Invaders

A homebrew Space Invaders style shoot'em up by Reed Byers aka Unbeliever. Released with source with excellent comments if you are interested in learning some assembly language. It's basically just a shooting gallery, nothing special. One row of targets that simply moves back and forth til you shoot them all, then they start a row closer, and faster. After five rows of the same enemy, you start a new "wave" of five rows, with a new enemy. After four waves, you start back with the first wave. Your only score is your hit/miss ratio, and your enemies can't shoot back. If you want to take a break, just walk away from the game; the enemies will be happy to wander back and forth until you're ready to shoot them some more.

Every single sprite is animated; even your shot. Every enemy type has its own explosion shape. There are simple sound effects for shooting, and explosions.
