Play Karoshi Mario Online

Karoshi Mario is a homebrew game for the Super Nintendo Entertainment System, developed by a small independent creator. It appeared during a time when hobbyists were starting to explore the potential of the SNES beyond its official library, offering a different kind of challenge for players who had exhausted the standard platformers.

You control Mario, but the goal is inverted; instead of surviving, you must find ways to make him die on each screen. The game is built on a series of single-screen puzzles where you navigate hazards and manipulate the environment to achieve a fatal outcome. You might jump on a specific enemy, trigger a trap, or use an item in an unexpected way. The puzzles require a shift in thinking, moving quickly from one solution to the next. It feels strange to actively seek failure, but solving each stage provides a distinct sense of cleverness.
