The good parts are so good but the bad parts really rubs me the wrong way. The first 2 or 3 levels were great, but I find the levels and sections that require precision platforming with insta kill pretty bad. I really dislike the precision sections with tiny platforms, considering that the controls are super sensitive, the failstate shouldnt result in death.

The desert and volcano levels were particulary bad on that regard, and I was about to drop the game after the volcano zone, then I started the Egg Rock zone and the act 1 was SO FREAKING GOOD that I guess I'm sticking until the end. Damn, the good bits of this game are GREAT. Also I've accept that I should use the Tails flight (playing with Sonic + Tails) to cheat on the bullshit platforming parts and there is nothing wrong with that.
