The easiest way to get out of the water and back in the game, at least in my opinion, is to walk all the way to the east, let the map wrap around, and go south a bit. You'll be all the way to the left of the map, about halfway down, walking on empty ocean. If you're lucky, you can walk into the "?" section of the map, and be transported to somewhere underground. I made it into the abandoned mines near trellis, and managed to not have to start from a save.

When you walk on the water near Koka Island, there's a little island in the river with a red potion and a staircase down... does anyone know how to get to it?
