PongRPG, my first XNA game, is finally available for download on my website here.  There may still be some bugs in it but hopefully it's nothing that makes the game break (if you find anything let me know).  The game is for PC and unfortunately will require a full install of XNA GS (which means you either need to have Visual Studio 2005 installed, or you'll need to install Visual Studio C# Express Edition, sorry!).  If you have time please check it out and let me know what you think.
