This was actually quite enjoyable, even if there were only 2 levels (or something broke in the second one). Some things I'd change: multiplying the force given to the ball depending on its size (bigger balls are currently harder to push), maybe changing the color palette button (at first I thought it depended on *where* you clicked, and was so confused when the "pink" button gave me a red and green palette), and disabling normal controls when you're clicking on the buttons, because every time I wanted to change something and the ball was in mid-air, it would just stop. That's apart from more levels and customization options of course, I wouldn't say this is the most customizable entry out there.
