Woo! It's exhilarating to see people playing and enjoying this. I just updated the game - it's no longer possible to cheat so easily.
If you want to shoot things, too, you might be interested in http://nottheinternet.com/games/spheres/ - where black spheres interfere with the cubed purity. Should I upload this to Kong, too?
Oh, and yes, you guys, music should be added. Any suggestions for something with suitable aggression (that I can license for free)?
