Play Yuki-Onna (super mario world hack) Online

Yuki-Onna is a 2012 Super Nintendo Entertainment System hack developed by Yogui, built from the foundation of Super Mario World. It arrived long after the SNES era had ended, a product of the dedicated fan community that kept the system alive through ROM hacking. The game takes the familiar mechanics of its source material and twists them into something far colder and more deliberate.

You control Mario, navigating a series of frozen, screen-by-screen levels where the objective is simply to survive and find the exit. The signature mechanics involve careful platforming on ice and snow that can collapse or shift, avoiding new enemies like freezing ghosts and navigating environmental hazards such as biting winds. The pacing is slow and methodical, demanding precision over speed, with a difficulty that feels punishing but fair. It feels like exploring a familiar world that has been fundamentally altered by a deep and dangerous frost.
