I've completed this game so many times throughout the years. Every exit and all. One of my favorites but something that's hard to go back to with how many times I've beaten it and how many games I have and have yet to beat. My only complaint is where the spin jump button is located but on any modern emulation whether on nintendo hardware or not can be remmapped to a more apt location. Overall one of the best 2d marios if not the best. If you enjoy 2d platformers and somehow haven't played this you owe it to yourself to go ahead and dive in.
