It's hard to believe this game came out when it did. It still genuinely holds up today. The controls could use some refining in a few places, namely Mario's weird ass Ring Around The Rosy move he does when you try to turn around. My biggest complaint with this game is that Mario is literally too good for the levels. They don't make use of all his tricks enough. The Mario 64 Romhacking community, however, has more than made up for that. Check out SM64 - Decades Later for a good example of a masterfully made Mario 64 romhack.
