The most fun I've had with the "Classic" era so far; this entry is pretty fast-paced and fun to run through; the time traveling gimmick is pretty well done, but sometimes the level design doesn't really let you use it when you want to; I'll admit that playing as Tails is the better option for me, as it's easier to explore and find the generators required to make a "Good Future".

I suck at the U.F.O. minigame and I don't like it.

An upgrade from its predecessor, this entry feels more fast-paced, making the levels feel more fun to run around in; the minigames are more easy to understand, and they feel like part of the story, as they unlock the possibility to use Super Sonic.

Fun game, nice music, friendly difficulty; level design isn't very remarkable, specially for a game that is advertised as "fast"; the minigames aren't very intuitive, and they don't feel part of the story, unlike in other Sonic titles, so they feel tedious.
