Updated Region Map

[Cyndadile]

We could try making 81 a bit longer and moving down 82 to fit with 85 again. Initially 82 and 85 were the same, so we could do that again. If 82 and 85 attached, we could still have a pure desert route between Saharan and the Eye of Sand. Or the Eye of Sand could be the only purely sandy place.
Also, I'd like to work something out for 63-68. The Hoenn map (where all region are combined) has that darker blue. The Route around Aquapolis is a diving area, so it could use the darker blue. Then we could make 64 into a diving Route. We might be able to combine 67 and 68 by moving Triumph Spire closer. Do we really need two huge routes between the pokemon league and the closest town? Especially since there's victory road, too?
Once we decide on those issues, I'll redo the labels.

Why not? At this point everyone will have gotten HM[Fly] so it's not like the routes make healing hard, just travelling there intially.
