This is a two player game of elimination. The goal is to take the other player out of the game. The orange cat is controlled by the arrow keys, and uses (m) to shoot. The blue cat uses (w), (s), (a), and (d) with the (f) key to shoot. Once one cat gets shot to many times by the other's light boomerang, it will lose and the game will end.
I took the boomerangs from another program that I made. The look of the cat sprites is similar to the cat sprite in a demo program from scratch 1.4.
