The game plays similarly to the Game Boy Donkey Kong game, giving Mario the ability to perform handstands and backflips. There are several different environments, ranging from a lava environment to the classic construction site, and there are five different types - in the first, and most common, Mario has to pick up a Key and bring it to the locked door. At the second part of the level, Mario had to pick up a Toy Mario at the end of the level. The second one is where Mario must guide the Mini Mario toys to the Toy Box, and protecting them from dangerous environments. The third level is the boss level, where Mario must fight Donkey Kong in order to proceed to the next world. The fourth level is one that happens after the player beats the main game. The Plus game, which is a repeat of the Main game, is unlocked. In this one, the story continues from the main game, where Donkey Kong finds a new batch of Mini-Marios, but with their containers broken. In each plus level, Mario must activate a Mini-Mario in the level, which is holding a key, and bring it to the door. The fifth is an Expert level. In this one Mario must grab the Mini-Mario with the key and reach the door in a very hard level. Getting through the door beats the level, rather than sending Mario to a 2nd part.
