After downloading the game and trying a few levels I can say the game is so so. The ticker at the top of the screen keeping track of your time spheres is inaccurate to say the least. Once you hit 999 it wont show any more, and some levels you have to get at least 1,200 of them as part of the requirement, well how can you tell if it maxes out at 999? Good luck keeping count. The story line is half@ssed written, Mr. Hanky's voice over is atrocious, get on the Poop Train and find out. So is it worth the 800 Microsoft points? Download the trial and find out for yourself, but remember you cannot use their super powers in it. My opinion is it's a modernized Super Mario Brothers which has potential, but is overly lacking, at the same time it is fun to play so again try the demo and see for yourself.
