It's good. It would be even better if you had keys to switch the colors. Fumbling the mouse from one color to another was tedious, especially when things were moving fast.
Thanks for taking the time to offer input. I agree it can get a bit tedious in some areas. I've updated it to use the 1, 2, and 3 keys (or J, K, and L) for the red, green, and blue buttons.
