So I have no real history in programming games or programming in flash at all. I recently learned AS3 and the "prototype game" I was making to teach myself Actionscript turned into this cute little time-wasting minigame. Thanks much to ImpendingRiot for doing all the art and animation and finally, please enjoy this dumbass voice actor's first attempt at making a game from scratch.
Use your mouse. Click in the empty space to make an asteroid, then pull it back and release to fling it in the opposite direction like a slingshot. If your asteroid hits a white beam without first getting a kill, you lose 5 seconds off your timer.
That's pretty much it.
NOTE: If you have a Drawing Tablet or some kind of Tablet PC, I hear this game is even more fun with that! =D
