I am currently an indie game developer and my team is From Nothing Game Studios. We've just completed our first game, a little puzzle title called GravBlocks. Essentially, take Tetris Attack, remove the combo system, and replace it with a strategy system that's based on gravitational changes. And there you have it.
It is now available on Google Play for Android phones and tablets (newer hardware is better, old hardware can make the game chug as it was developed the Unity 3D engine).
