Mario vs. Donkey Kong is a game for the Game Boy Advance and was later published for the Nintendo 3DS as a gift from the Ambassador Program in 2011. The game finally brings back Mario and Donkey Kong's rivalry from the Mario series first game, Donkey Kong. The game's sequel is Mario vs. Donkey Kong 2: March of the Minis for the Nintendo DS. Some of Mario's voice clips are reused from Super Mario 64.
The game was first shown at E3 2002 as Donkey Kong Plus, which was like an improved version of Donkey Kong '94. (1994) The only known differences were the graphics and the player can make their own levels on the Game Boy Player, then using a link cable send them to the Game Boy Advance using a link cable. However, the game vanished the following year, until Mario vs. Donkey Kong came out, with the level editor gone and the graphics were replaced with pre-rendered graphics. However, the game's sequel, Mario vs. Donkey Kong 2: March of the Minis had this feature and took advantage of Wi-Fi Connection.
The game's story begins with Donkey Kong watching TV. As he flicks through the channels, he sees an ad about the Mini Mario toys. He is disgusted with them, but still, Donkey Kong falls in love with the toys instantly. He goes to the Toy Store, but they are sold out. Donkey Kong turns around and sees the Mario Toy Company and decides to loot the store of all of the toys. Eventually, Donkey Kong checks his bag, only to see all the Mini Marios he stole have dropped, with Mario, the toys, and three Toad employees laughing at him. In anger, he grabs the three Toads, climbs the building, and Mario must rescue the three Toads and fight Donkey Kong again. However, he must make his way through the six worlds to get to the battle on the top of the building. After the fight, he falls off onto a truck full of Mini Marios, and steals five more. Mario gives chase once again, until a similar cutscene of the one before the defeat, but only Mario laughs, until six Mini Marios come out. After that, it is the final scene. Mario is scolding Donkey Kong for what he did. Donkey Kong is crying in pity and shame. Mario cheers him up by letting him have a Mini Mario. The Mini Marios and Mario cheer with Mario's mission successfully done.
Each of the six worlds is divided into eight levels. For the first six levels within each world, Mario must find a key and open up a door to the second half of the level. There, Mario will find the toy that Donkey Kong dropped. The seventh level in each world is a Mini Mario level. Mario leads the six mini Mario toys he collected back to their toy chest; however, he must make sure they avoid obstacles along the way. This leads into a battle with Donkey Kong, with each Mini Mario saved becoming a "hit point". For example. If Mario saves all six of the Mini-Mario toys, he'll be able to be hit six times by Donkey Kong before losing a life. If the player fails to defeat Donkey Kong and chooses to replay the fight without doing the Mini Mario level, Mario will start the fight with four hit points.
After completing the six worlds, Donkey Kong will fight Mario. After being defeated, six extra worlds are unlocked, numbered 1+, 2+, and so on. In the Plus Worlds, Mario must get to a Mini Mario holding a key and lead it to the exit doorway. There is only one part per level in the Plus Worlds, and they are designed to be more difficult than the main worlds. There are still Donkey Kong boss levels in the Plus Worlds.
After completing all of the Plus Worlds, Mario fights Donkey Kong once again, for the final time.
