Sonic: Lost in Mario World

Sonic falls through a portal into a Mario-style world: run and jump over pipes and pits, collect coins and mushrooms.

How to play

Arrow keys: run, crouch; A: jump.

Click the game first so it gets the keyboard. P or Esc pauses; the speaker button in the corner mutes the sound.
