So I recently came across this map from this thread. Intruiguing, and suggests that if S3K were a Metroidvania, you might see direct connections between Angel Island & Marble Garden and Hydrocity & Lava Reef/Hidden Palace. But there seems to me to be just one area, the jungle(?)-like area right in the center of the island, that isn't represented by a zone - directly connected to Ice Cap, Launch Base, Marble Garden and Sandopolis. Has anyone else noticed this before, come up with any kind of theories to do with it, or possibly even toyed around with the idea in a hack?
