I picked this game up because it was just about the only fitness app I could find that didn't require a subscription. I wasn't expecting much due to being only available on app lab, but I was surprised by how well the game played. The graphics are great, sounds is great, and the amount of songs is great. There are four available environments to workout in which are all beautiful. What really blew me away is the customizability. For each song you can choose 3 or 4 difficulties, however you can also choose how often and complicated moves like punches and squats will be. Where this really shines is you can easily add your own songs and the game has a pretty sophisticated song analyzer that will auto generate a workouts based on beats per minute.
