I tried it on my Nexus 7. Gameplay was not bad, especially for your first game. Congrats and keep on going!
For some reason the game crashed after 4-5 levels. Not sure why. Thought you should know.
Also, I'm testing a game on Android, and for some reason when I install my beta game, my device lists a few things that my game wants access to. But your game didn't require access to anything on my device in order to be installed, which was nice. Do you recall doing anything to make it that way?
