Marble Zone (Legacy), Sonic Speed Simulator Wiki

Marble Zone was an unfinished world that could only be found out of bounds via glitches. It, as well as other unfinished maps, was removed from the game on April 15, 2022 to allow the game to run smoother. It is inspired by the zone in Sonic the Hedgehog (1991) by the same name. It has white grass, but that is most likely non-intentional.
