There are 6 baddies, 3 of them can shoot you, these are the red ones, the other black ones don't have guns. press space to drop a bomb and arrow keys to go left and right, aim of the game is to eliminate all of the baddies.
I made all the code, and the very badly drawn sprites were also made by me. (if you look inside you will see all of my comments on how the code works on each sprite)
