This is the Ludum Dare 48h version of the game. Hopefully the Java4k will see a proper (fun) version of the game, with a couple of new elements to it. As I have been unable to get pack200/gz to work for this contest, the class file that's run is larger than 4kb. However, the compressed version is significantly smaller than 4k, despite not being fully optimized.
