Oh, and protip: you can use the tiles that go along the top edge of the ramparts along the tops of all the horizontal ramparts. Might clear up a little graphical discrepancy in this otherwise awesome map.
@Liberty - Meiscool, remember her. She's the one who made this tile set. Also I'm pretty sure none of what's shown on this game page is even associated with its current form.. Except maybe his art I don't know.
