After the price drop and the patch it might be worth it.
The patch made it much less frustating with 100 rings = 1 life and analog stick controls instead of gyro controls for some wisps.
I think it's a good game (8/10 for me), but maybe not what most Sonic fans expected. It's like a mixture of Mario Galaxy, New Super Mario Bros. and sometimes Donkey Kong Country, but with more speed and less polish.
Graphics and music are pretty good.
Level design between mediocre and excellent.
Controls are a little strange at the beginning, but they work very well after a while.
