Easily one of the best Mario games I've ever played, and certainly one of the best Mario ROM hacks I've ever played. Hell, I'd almost even put this over Super Mario: Star Road. The creativity, the charm, the well-designed levels, even the new additions such as the shops and the new challenge houses are all well-made and thought out. I can say without a single doubt that these creators understand Mario and it's design better than almost anyone else. The only things I can think to criticize are the visuals, the re-used bosses, and the absurd difficulty spike that occurs after you reach the space levels – Like you can feel the game go from "normal" to "hard" very quickly, and it just keeps going until near the end where it reaches "testicular torsion." But even there, the game still feels relatively fair, and if you bother to look for the switches and shortcuts, the difficulty can at least be lessened.

But the biggest compliment I can give this game, and the one I'll leave off on, is the sheer sense of adventure the mostly inter-connected world map provides. I'd recommend this game to anyone who enjoys Mario (and who doesn't?) for the sense of adventure alone. Even if not all of the ideas are good, the game never stops trying new and creative things. And I love it for that.
