Just press the green flag and watch as sprites either move around, reproduce, kill each other, fly a plane by, or end it all. Update 1.1: Civil War * New evolutions: Plane cat, flies by and drops lime cats. Purple cat, no legs and spreads like a plague for some reason. Pink cat, tank, can shoot ballistic missiles but doesn't reproduce. * New sprite: Evolution 1.1 now has a grand total of two sprites. The new sprite is tank cat, aka pink cat. * Sound effects: Now added so that you can listen to a cacophony of planes, lasers and explosions.
Just bored me deciding to make something really complicated.
