It's essentially the same level that all Sonic levels are, only dressed up slightly differently - complete with a mostly way too easy Robotnik boss battle (that eggman survived way too many explosions) - and pretty much only qualifies here because it looks so damn pretty. And I suppose the fundamental model that drove all of Sonic's early levels was good enough to just about justify the perpetual recycling, before Sega foolishly went 3D with the hedgehog.
