I played this game through the Sonic Origins collection on Switch. While this game starts with a zone that does a great job at letting the player play with Sonic's speed, I find that the level design as a whole drags this one down. Other than Green Hill, the only other stage I enjoy is Star Light Zone, but even then I still think this game peaks in it's opening act. The rest of the zones are either forgettable or complete slogs to run through. Marble Zone and Labyrinth Zone stand out especially, with the former's reliance on waiting and the latter being one of the worst water levels in a series with a lot of bad water levels. Also shout out to Scrap Brain Zone for having it's third act be another run through Labyrinth Zone, gotta be one of my favorite things.
