Don't really know how to leave a comment in reply to another. But thanks a ton for you feedback! I agree with the colors. I need to start learning what colors go well together. Holding the button currently speeds up the balls on screen, as a way to fast forward. We tried to teach this in the level "Hold To Go Fast", but as I learned fairly quickly with this game, it's really difficult to make sure players understand a concept before moving on. A valuable thing to learn! I'll check out your game and see if I have some feedback for you.
