I'm sure at least a few of you have tried that Bit Trip Runner game. It tends to be either free in the Humble Indie Bundle, or incredibly cheap during steam sales and sitting on the front page. (I think it might be for sale now actually).
Anyway, have that in the first slot, and a simpler Applejack running through the forest in the second just because.
