Just submitted my entry, Ghosts Overboard, a collect items game controlled by tilting the device.

I didn't come up with a good new idea, so I recycled the idea and graphics from a never-released desktop game I made two years ago. Because of the chain of changes resulting from a move from keyboard to tilt control and the horrible design choises of the original version (it was slow even on the desktop I had back then), I decided to rewrite the new code from scratch.

Since the original game was never released, I assumed this one would not be considered a "port" and wrote nothing on the existence of the old one in the competition entry. I'll be happy to change that, though, if required.
