My baby and I tried your game, it's a pretty fun puzzle game although initially we were a bit lost on what to do, but we were able to figure it out then it's enjoyable. More directions/tutorials hints for the beginning player would be great. I can see this idea flourish very well on Android/OS market if you ever decide to take it to commercial markets.
