This works really smoothly on Android. Nice job on the technical aspects!

One suggestion I have is to make the game more challenging by having a target number of moves the player should stay under and award points based on that.

Could easily be a 1-3 star score per puzzle. Then players can race through with any star count and go back to get the optimal solutions.

For now the level number you get to is sort of your score, There are a lot of levels, and some players are already around level 400 :-) (no analytics, just from my social circle) being able to scroll back to get a level from 2 to 3 stars does not seem like a good effort somehow. But I will think if there is some way to measure differences in play, if that is really interesting to know.
