NOT EVEN CLOSE TO DONE WITH THIS SUBMISSION LOL Right now the pathfinding is, well, less than stellar. You'll probably have to press the green flag a couple of times to get it to do something other than pirouette. That's okay though, the main point of it right now is to try to map out the world. Check out the list "mapInMyHead" for details (it's too big to fit on the screen alongside the other lists comfortably, so I've hidden it)
This is my favorite challenge so far, thanks! I'm sharing this project even though I'm not even close to done because I want to remind myself to work on it later and not let it rot in my My Stuff. ;P
