Yes - Robot Unicorn Attack is similar. There are some differences in game play and we have an objective system (quests) along with some predefined levels to distinguish it. Hopefully more levels will be included in the first update.
In any case, the game itself was not my idea. All the art, sound, concepts/design etc was put together by MindJuice Media. I did a lot of the development work - primarily for gameplay and menus. It was a fun project. We used a new-ish "flash-like API" library called Pixelwave
and Box2d for the physics.
