Pretty great game, just wish it had better controls and a couple more levels. I love the unique gimmiks, multiple playable characters, bosses, and the level design is pretty good with a couple exceptions. In my eyes, this is the true sequal to the original Super Mario Bros because this one is not only good, but it also dares to expand the universe and introduce new concepts never seen. Probably one of the most underrated games in the series, despite it's flaws,
