I finished my first game, and it's called Kuatro. It's a tetromino-based arcade-puzzle game. I made the game from (mostly) scratch with Unity 3D, Sunvox, and Audacity (Photoshop helped too).
You can purchase the game from both Gameolith, a multi-platform digital game distibution site, and the Mac App Store.
See the Kuatro page for more info.
I created an original soundtrack for the game, which you can listen to
right here!
