And I don't see why you think all the "Genesis:" areas are interconnected. Nothing says or suggests this, nor is it suggested they can teleport people around.
As such, why does the island have two separate areas of the same name with such a large gap between them? What's the point in going to the latter area when all it does is effectively teleport you to Genesis:Water through Genesis:Earth somehow, despite G:E being under sandzone, underwhich is the bottom of the island, and yet somehow Gen:Water is next to/below it, this only being the result of Shmitz assuming the Labyrinth HAD TO be close to Sandzone, which HAD TO double back onto itself in some way. Because the island is apparently two-dimensional, and looks like a pong rectangle from the side.
Now I'm not saying the G:W area can't be connected to Sandzone somehow, but I highly doubt such areas would exist immediately beside one another, just as I highly doubt mimiga village is BELOW sandzone, while simultaneously to the far left of it next to Grasstown. The map as-is in this case is
[Mimiga Village] [Grasstown] [Labyrinth?] [Sandzone] [Water Area?] [Labyrinth??] [Water Area!?]
[Spirit Area?] [Graveyard??] [Mimiga Village?!?]
And then it just gets confusing.
Now, the reason we can rule that the aqua area is next to the sand area is twofold: the tileset is the same, and both streams end up in the same general location. The reason we can rule Grasstown is next to Mimiga village is because of the simple connection between the two (as well as a lot of fan theory), and the reason we can rule G:W is above or beside Mimiga village is because... well, it's entered via the reservoir.
What I'm doing at the very least of this is spacing things out a little more if only to make the island feel as big as it felt in the original game. If we're to believe that Genesis and Oblivion have truly been expanding the island, then these such rough connections should be further away, not closer together. In the original game it isn't implied that the waterway is IMMEDIATELY above Mimiga village; if anything it's far, far away from it, and happens that an artery of water passes by, or branches off overhead. Although ultimately all this does is serve to show that even the map connections I'm keeping intact are nearly impossible, but let's assume that the labyrinth, at the very least, got pushed toward Mimiga Village.
Still, most of these 'Well they just HAPPEN to be next to one another!" concepts are highly unlikely. But, nonetheless, they're there as a method of serving the way the new story develops. And "Get to Balrog through Genesis Spirit which goes to Genesis Earth which goes to Genesis Water" is a really bullshit stretch.
I'm centralizing the locations in the game to one distinct location each. I'm not saying that it's unlikely these places would blend together (hell, they SHOULD be blending together if anything), but it's unlikely that they'd be connecting to one another in the way that Shmitz intended, but never actually explained. And all this lack of explanation hurts the game.
Genesis:Spirit is being centralized in its location under the island where you'd find King's sword. All these such events will occur there, after which is the only pity-teleport back to the Genesis:Earth area. Which is why I'm moving Balrog around, to make up for it. I've a different plan for that door in the graveyard than just a crummy throw-away area.
