Overall a pretty fun game, but it definitely has some frustrating parts. In particular, Rogue and Knuckles have some very irritating levels, but I mostly liked the different gameplay styles. Sonic and Shadow of course have awesome levels and I also really liked the levels Tails and Eggman have. I would've rated this game three stars, but the Chao Garden alone bumped it up half a star. I've spent so many hours in that mode and I wish SEGA would revisit it for a new Sonic game.
