Interesting concept! Simple level design makes things easy to understand what to do. I would set the background to not be as strong as the foreground as it can sometimes be difficult to distinguish the player from the background.
I think that you would benefit more from adding some sort of jump mechanic than adding enemies, as the levels can be sometimes difficult once in the valley of the sine wave.
Hey! Thanks for playing, while the arms not reaching the buttons is actually an intended feature (For the selected ages of 1 - 16), the screen size however is not! Could you tell me the size of the screen you were using?
