The overall play of this game is good. I was able to build up a sweat on the workout. The one thing that kept driving me mad was the timing issue. When you box, there seem to be a delay in your actual movement, and the movement on screen. It was the same way with the balanced board. And other thing was, that my movements where actually backwards on screen when using the balance board. So i had to flip my board around. That was annoying.
However i really did like the workout part, and if the timing was better, i would purchased this game, instead of returning it on the 3rd day of the rental.
