|This is a FanGame by 77 Heru's Inc.
Gameplay is very similar to Doki Doki Panic/Super Mario Bros. 2/Super Mario USA. Though it has some changes, such as a multi-player Co-Op, More characters, and the ability to switch between characters in-game. There is also a sidekick feature, similar to the Helper feature of Kirby Super Star/Kirby Super Star Ultra, only it does not involve using enemies, and you can't recall them(well technically it does, but they're not enemies in this game).
