I made a little 3D Platformer for Anroid the last half year called Morphball. The game is free with Ads and has Leaderboards from Google Play.
The game is almost finished, what would interest me most is if it runs on your Device. So if you like, just click the link below to register for the beta and mabye drop a few words here how you like it.
