Thank you very much! I know it's stretching the rules a little bit, but I did upload a new version to fix the performance. The background used to move (the kinda smoky stuff), but apparently generating noise textures is really bad for performance on web. It always worked fine locally, so I didn't know about it until I uploaded it a few hours before the contest was over. I hope that's OK, because it didn't change any of the functionality, it just made it playable on the web. It was just changing an option under the texture and turning off the timer that was used to move it, so two little check boxes, and the performance is now fine.

If I had more time, I was going to add buttons for the size of the ball, which would change how much the numbers go up or down, and as it is, you can switch between ADD and SUB that add or remove the color from the mix. Technically, right now, each basket adds or removes 16, since colors are in hex format.
