The greatest game boy game ever made. Im not lying and if you disagree, you are wrong and dumb. Still holds up to this day with incredible level design, cool music for the game boy, and the tightest feeling 2d mario to ever control. It has so many different level ideas that games like new super mario bros would claim as its own. The mini mushroom makes it first appearance here and its used way more interesting than any mario game in the future. Side flipping through levels is so insanely satisfying, you can clear some levels in less than 10 seconds. I'm gonna say it, i will say it. This is the best 2d mario game.
