Atari Invaders

Atari Invaders is a wonderfully simple, smooth, and colorful adaptation of the classic game Space Invaders. Better than many others.

It says "Insert JJoystick" on this screenshot, but that's not a typo. If you wait long enough, an Invader comes out on screen to bomb the extra J away. This is an homage to the original "Space Invaders" coin-operated arcade game in which the writing "Insert CCoin" gets its extra C bombed. That's how truer to the arcade this one is than the others.
