I tried to play this game at the weekend but ended up giving up after about 20 minutes. Compared to the Adventures game, this one doesn't seem to be as interactive and is definitely less responsive (and considering that's the essence of a Kinect, seems like a complete let down!)
The tutorials are not very helpful - I couldn't complete the jumping tutorial, it gave no indication of where I was going wrong just kept saying that it wasn't easy. I was jumping when instructed and even though I seemed to be getting good ratings (not sure how these were worked out!) I couldn't get past it.
the menu is also annoying, with a sweeping motion that was hard to control. i had to resort to using the controller in the end.
So, I skipped that tutorial and eventually managed to choose the option just to the game. What was very frustrating is that despite swaying from left to right, Sonic just didn't seem to respond. I'd put my arm out to catch rings and it would just pause the game.
very frustrated with it and I will be trading this in as soon as I can.
