This game is actually very fun. The gameplay is a lot like the super mario games on gameboy. It is different though. Because you are battling other players. It is up to 4 players, and it has AIs that are very hard on the difficulty 'Very Hard'. You can make your own maps and what not. If you need help just check out the forms. The like that I gave you is to the 1.8 beta. If you want the old one go ahead and find it, but I don't know why you would. Check it out, because if you are here, you have nothing better to do. It works on Windows, Mac, Linux, and X-box.
