Play Karoshi Mario Online

Karoshi Mario is a Super Nintendo Entertainment System (SNES) homebrew game, developed by an independent creator rather than a major publisher. It stands out among the platform's library for its deliberate inversion of typical Mario gameplay, turning familiar mechanics into something darkly absurd.

You control Mario, but your goal is not to survive or rescue the princess; instead, you must find ways to kill him in each level. This involves running into enemies, jumping onto spikes, or triggering environmental hazards like falling blocks. The game progresses screen by screen, with each stage presenting a new puzzle of self destruction. It moves quickly, and the challenge comes from figuring out the specific sequence of actions required to die, which often plays against every instinct you have from other Mario games. It feels strangely satisfying to dismantle the hero's usual purpose through such deliberate failure.
