I have a completed game that could use re-skinning. If you look at my profile, you can check it out: Ace Escape. The version in my profile is old and might have a bug or two, I'm not sure if I ever put up the final build. I had it up on FGL over a year ago and got some sponsorship offers in the $300-$400 neighborhood, but I never followed up. I think with a complete re-skinning and new levels, it should be able to score more offers on FGL, but I don't expect to get rich on it.
I am also working on a sequel with many more advanced features, more puzzles, a map screen, and so on, that I hope to eventually put up on Facebook.
