Play Mario Vs. Donkey Kong (J) Online

Mario Vs. Donkey Kong (J) is a puzzle-platformer where you chase DK through toy factory levels, rescuing mini Marios he stole. The first few stages ease you in with simple jumps and switches, but then the game starts throwing conveyor belts, disappearing platforms, and enemies that force you to think ahead.

I remember one level where I had to time my jumps between moving platforms while dodging fireballs, only to realize I needed to backtrack for a key I missed. The controls are tight, but some of the later puzzles get brutal, especially when you have to herd all the mini Marios into the toy box without losing any.

It's a clever mix of platforming and problem-solving, though the difficulty spikes can feel unfair at times. Mario Vs. Donkey Kong (J) nails that old-school challenge where every mistake stings, but finally nailing a tough stage feels great.
