Play Super Mario World (lost levels prototype) Online

Super Mario World (Lost Levels Prototype) is an unreleased version of the 1990 Super Nintendo Entertainment System game, developed and published by Nintendo. It exists as a curious artifact from the early SNES era, a time when developers were still exploring the hardware's capabilities and players were getting used to the console's signature mode 7 effects and expanded color palette.

You control Mario or Luigi, navigating side scrolling stages filled with platforms, enemies, and secrets. The main objective remains to rescue Princess Peach from Bowser, but the path is radically altered. Signature mechanics include navigating treacherous, often disappearing platforms and dealing with enemy placements designed to surprise and challenge even experienced players. The pacing is deliberately unforgiving, demanding precise jumps and quick reactions. It feels like playing a familiar song where someone has mischievously changed all the hardest notes.
