I'm not sure how feasible this actually is, but I would like to see some sort of border between the regions. I understand that some areas transition into each other nicely, but many don't make much sense. Imagine having a bridge street in between Groddle Heights or Alakol, or perhaps a dock with a small ferry that could be activated like a signpost. Maybe in other areas a gate with a fence that you would pass through to signify the transition? I think it would give some oppurtunity to add more flavor to the areas, the swamp could be a broken creaky dock or something. One bridge street, or perhaps a dock street on either side would do quite nicely to bridge the islands. It might also help with a sense of direction for new players, I often found myself wandering far from home without realizing it
