This is actually the Xbox live arcade version (one that wasn't finished) and I've heard the game is not really like this on wii, however the graphics haven't changed. So the graphics in the video will mostly what you'll get in the wii version too.
I'm not sure if this is anything more than pictures of the game. (as Videos no longer work on my computer because it's useless -_-)
But I think it has music from the game.
