I think Apple has been trying to push there iPod games by convincing game makers to make Demos of there games for free. The first was Vortex and now you can get Ms. Pacman.

Its free and I played it for a little bit, even though there is only one level. I really like the interface, to control the direction you just touch the side of the scroll wheel where you want to go. Its really easy to pick up and play and I suggest everyone go out and try it out.
