Mario vs. Donkey Kong

Mario vs. Donkey Kong was released by Nintendo in 2004 for the Game Boy Advance, arriving during the handheld's mature commercial phase — the GBA had been on the market for three years and its library was rich with polished first-party titles. The game serves as a spiritual successor to the 1994 Game Boy title Donkey Kong, itself a reimagining of the original arcade classic, and it carries forward that game's emphasis on puzzle-platforming over pure action. The premise is straightforward: Donkey Kong steals a batch of Mini-Mario toys from a factory, and Mario must chase him through six themed worlds plus a final showdown to reclaim them. Each world is split into two distinct phases. In the first phase, Mario navigates a traditional platforming stage to collect a key and unlock a locked door, using a move set that goes well beyond the standard Nintendo platformer — he can perform handstands, backflips, cartwheels, and hang from pipes and ledges, giving the controls a surprising depth that rewards experimentation. In the second phase, the locked Mini-Mario toy must be escorted to a toy chest, introducing light puzzle mechanics as players manipulate the environment to guide the small automaton safely to its goal. Each world concludes with a boss fight against Donkey Kong himself, which plays out across multi-stage arena encounters that escalate in complexity as the game progresses. The level design is compact but inventive, making strong use of the GBA's hardware to layer switches, moving platforms, enemies, and environmental hazards into stages that can be completed in a few minutes but often require careful observation before acting. The game was received positively upon release, with critics praising its clever blend of action and puzzle-solving, the variety introduced by the two-phase structure, and the high production values including expressive sprite animation and a lively soundtrack. Some reviewers noted that the game's overall length was on the shorter side for a full retail release, though the inclusion of bonus stages and score-attack incentives added replay value for dedicated players. Mario vs. Donkey Kong established a framework that Nintendo would revisit and expand in subsequent years, cementing its place as a notable entry in the GBA's first-party catalog.
