COLORbox Update

Well, I finally got around to doing a new version of the COLORbox. The main changes are a new level system that add new colors to the mix as you progress through levels and support for using the a, s, and d keys (rather than the arrow keys). It definitely adds a bit of challenge, but I think it makes it more fun. Anyway, let me know you think. Feedback is always welcome. Thanks for visiting!
