Simple: Remix and continue. Oh, and some rules: 1) This is not a game to win. It's simply something for fun. 2) Please limit your power. 3) Keep it somewhat tidy, not fully 100% perfect but it's a map, so it needs to be somewhat accurate. 4) Artificial islands (or islands you add) must be in grey and must not be bigger than the triangle islands you see already.
