Play Super Mario World Death Land Online

Super Mario World Death Land is a fan-made hack of the original Super Mario World, released on the Super Nintendo Entertainment System by Nintendo. It exists outside the official library, a product of the dedicated ROM hacking community that emerged long after the SNES era had passed. This mod takes the familiar foundation and twists it into something far more demanding.

You control Mario through a series of remixed and entirely new levels, with the objective of simply surviving to the end of each one. The gameplay hinges on precise platforming, memorizing trap placements, and executing pixel-perfect jumps over bottomless pits and instant-death hazards like lava and sawblades. The pacing is relentless, and the difficulty is unforgiving, demanding repeated attempts to learn the specific timing and enemy patterns of every screen. It feels like a brutal test of patience and skill, where every success is earned through failure.
