I very much had a similar experience to the review below. Menu screens are quite hard to naviagte with the Move controller and there are no explainations about each part of the Menu.
I thought the tutorials would give me an intro into the game but it goes straight into the steps which don't really help when you do a routine. I also seemed to have the problem that my move controller wasn't being picked up properly and wasn't recording what I was doing. Very demotivating when your stuck in orange section no matter how much you move your hips.
But saying that it was still a very good workout! The steps were very fast and it took me a few goes at a step to get it right (by which time it had moved on).
If my responses were picked up better by the camera and there was a better 'beginners' section I think I would get on a lot better with this game
