Picked this up today and played it all the way through. The game is awesome, feels a hell of a lot like the old Sonic games, but with a little bit of over-the-topness thrown in that gives it a lot of energy. Definitely pick this up if you liked the original.
This video has all seven Special Stages. You control the stage by rotating it around Sonic with the control stick or the D-pad. You can also make Sonic "jump" by pressing the A button to tilt the stage while Sonic is touching it.
