Interesting design! The controls takes a lot to get used to and I found the bouncers to be unreliable and would sometimes not bounce me sometimes. Also I think it would have been better to maybe have a few easier levels first and then crank the difficulty on the later levels.
It might be that I am just terrible at your game but I had really hard time to even pass the second coin on the first level.
But I really liked the idea of the game and the execution!
