One of the most unique Mario games, which isn't a surprise if you know the history behind it. As a result it does offer a ton of neat mechanics like riding on enemies to traverse the level.

The ability to play as 4 characters, each with unique attributes, is also a neat touch that even later games in the series wouldn't implement for quite a while.

Despite the fact this is the game some countries got because the real Mario Bros 2 was too hard, this game isn't really a cakewalk either. It offers a decent challenge.

It's still not an amazing game, but it's different, fun, and for a NES game aged quite well.
