Great and unique concept, not the best execution.
1. You can throw multiple balls at once - that can allow beating the puzzles in an unintended way.
2. There's no limit to how much gum you can place - there's no difficulty.
3. In contrast, the chances of the ball falling into the bucket (or flower pot? it looks like so) are 1 in an Impossible. You should place it somewhere else.
4. Some obstacles would add depth to the gameplay.
5. Graphics are great, but quite barebones for what it is. You could include some more detail in the stars, or the board (I think some goofy scribbles would fit it!).
6. Sometimes the ball doesn't react at all with screws.
Also, am I the only one who finds the fact that the kid can stretch his arm to infinity funny?
