It's astounding Sonic was marketed as fast when Labyrinth Zone might be the slowest level I've ever played. While it's technically impressive and has some good music, the level design is too woefully inconsistent for Sonic to be heralded as some great game.

Not terrible, but not the flagship title for the Mega Drive like SEGA hoped. The Mega Drive has many, many better games, such as Sonic's own direct sequel.
