I love Sonic 2 and 3, but Sonic 1 is mediocre at best. The level design is littered with bullshit made to screw you up and stages that completely break the pace of the game. People love to dog on Labyrinth Zone, deservedly so, but going from Green Hill to Marble Zone is the biggest whiplash in the history of gaming, ESPECIALLY considering how this game was marketed in the 90s as super fast paced and dynamic while Marble Zone is the antithesis to all of that. Forever the worst classic 2D Sonic.
