Because the Zones in Sonic 4: Episode 2 are mixes of other zones in Sonic 2, I thought the zones in Sonic 4 Complete could be mixes of other zones in S3K. In that way, Mushroom Ruins Zone could be a mix of Mushroom Hill and Marble Garden Zone.
It took forever to make these, so I'm going to make another project with more sprites. The sprites are totally original, no tracing done, so please credit me if you use them. Obligatory Tags #Sonic #Sega #4 #Sprite #Sprites #Art
