I just think the whole program sucks! It's definitely not a science. It's actually quite frustrating. I think it's a UBISOFT (THE DEVELOPER) because a friend bought me Just Dance, another of there games for Wi and it doesn't respond either, and there's no camera. But in both cases if you disregard all of that and keep moving you'll burn calories and/or have fun. But in both cases I would definitely no recommend to someone.
