It looks pretty nice. Probably would find a home in the 4.99 market (I say this because you mentioned it will be for sale).

I do have a few nit-picky suggestions, though, so please forgive me. The over all UI is a bit dull, being grey with a little texture. Perhaps this is only one level??? Also, the text, for the time, score, ect. dosent look like its aligned correctly. Easily fixed, but just figured I would point it out.

Other than that, looking good. Keep with it, and you could have an entertaining product when finished.
