Ok so I played I for about a hour. I have enjoyed it so far. Ok Flames before you start a song you can press the a and b buttons to determine what wiimote controls each of the robots hand. So I have a wiimote in each hand so I press a and b on the left to use my left hand to match the robots left hand.Vudu that is a minor problem, but is similar to DDR because you have to keep a eye on the arrows while timing your movements. I think it is a bit easier to manage in this game. You start with 5 songs and you unlock the rest by how many songs you played.I personally like this game. Even when I am not doing well, I enjoy it because of the music. Vudu's point stands. It is somewhat difficult to keep your eye on the robot and the timing bar, but if you can adapt to it then you will do great. All in all this is a great game with a minor fault.
Edit: I made a mistake on how you unlock songs.I had A rank. Now I have songs played.
