one of those games that sits comfortably in my library on virtually every system i've been able to lazily grab it on. i probably know every inch of this, cd and sonic 2 like the back of my hand. about half of this game still holds up pretty well and i think i'm used to marble zone enough to fly through it but god damn if labyrinth and scrap brain aren't egregiously designed. it's a decent early genesis platformer, you know? i think cd feels like this game with more identity and creativity, and then sonic 2 is kinda the first proper "sonic game" but this one's alright. i feel like everyone ever has already played it but if you're bored with the other classic sonics give this one a spin.
