I decided to merge the multiplayer/non-multiplayer versions so just download Pong.zip for either. The multiplayer has no impact on singleplayer play so it doesn't really matter. Also, I added a little menu that comes up when you pause the game that allows you to pause the music as well as all the other options from the music menu(choose playlist, artist, and whether or not to shuffle) Also, the context menu somewhat parallels the one the zune normally has so it looks pretty nice
