Hello! I´m using YS a lot and I dont know if I can give some sugestions here but anyway ^
1) In the "Running World" excercise your guys should put textures! It would be really nice to play. And too, add another landscapes like grass roads, farmes, and forest.
2) We need to change players more easly. Why you guys dont use the kinect recognition to change the player? I and my wife are using this game a lot and we dont have a back button to return to first screen, we need to go to options.... it is very annoying.
3) Games like wall breaker are really cool ! Put more workouts like theses!
4)Keed that good work!

Thanks.
