I just recently finished developing my first android title, HazManiac. It's an arcade sidescroller shooter with graphics inspired by the early Worms games.
The project was a two-man game, and I did all the visual stuff and most of the audio work. It's not the fanciest thing ever, but rather a playground for us to sink our claws into mobile development.
The game is available for 0.99 at GooglePlay. There are few known bugs that we're still working on. The online high score being one, which we'll switch to local highscore in the next version. https://play.google.com/store/apps/details?id=com.grm.hazmaniac
Any feedback is welcome! We'll probably move to a different genre after this one, as sidescrolker sets its own technical and artistic limitations.
