This is one of four boards in my roll-and-move RPG (still working on it). It was meant as a theme-sequel for a publisher, but the idea hasn't stick so far.
Anyways, in case you haven't notice, it's supposed to be a Castle. From many illustrators I've spoken, most think it's undoable. Still, you can get the idea of what I'm trying here (don't make me explain it in English...)
Keep thinking!
