Builds upon everything that the Hedgehog was known for already, while perfecting multiple minor issues along the way. From Sonic continuing to run during the 'End of Act' screen, to the little touches of amazing, thought-through animation when Sonic is hit by a falling capsule, everything in this game obviously points back to developers who finally found what they are good at. The only downsides are the music (it is a GBA game, to be fair) and it as a whole being slightly on the slower side for a Sonic game, which isn't necessarily a bad thing.
