Sonic Lost in Mario World

Sonic Lost in Mario World is a fan-made modification of the original Super Mario World game for the Super Nintendo Entertainment System (SNES). The mod features Sonic the Hedgehog as the playable character and replaces Mario's abilities, sprites and sounds with Sonic's. The game's story is similar to the original Super Mario World, where Sonic is transported to Mario's world and have to rescue Princess Toadstool from the clutches of the nefarious Bowser, but with a new adventure and challenges.

The mod includes new levels, enemies, and power-ups that are based on the Sonic series, as well as updated graphics and sound effects to reflect Sonic's style. The game also includes new moves and abilities for Sonic, such as the ability to run at high speeds, spin dash, and jump high in the air. The mod also features new enemies based on the Mario series, such as Goombas and Koopa Troopas, but also enemies from the Sonic series like Eggman's robots.
