It's like Space Invaders... but in reverse. Instead of controlling the lone ship firing at a swarm of aliens, you control the swarm of aliens dodging the lone ship's lasers.
Use the left and right arrow keys to move the alien swarm left and right. Also, keep in mind. Since you're playing as the bad guys, moving to the next level is actually bad, while getting a game over is actually good. At the title screen, press C then S to begin (it'll make sense when you see it).
Oh, and there's a 2-player mode you can play by pressing C twice. The second player uses the A and D keys.
Splat... Splat... Splat... Splat... Splat... I feel you're kinda at the mercy of the random number generator, as it's basically impossible to defend yourself if the tank shoots near you. But fun game. I would have voted up on humor for the sounds. :P
Quite a nice idea ^^ It was very challenging >.< I guess because the invaders took so much time to go down. The defender AI was a bit dumb, sometimes just keeping itself in the corners, although a good AI would make it very very difficult. Great work!
It was fun to play.
