See instructions at beginning, pretty simple. This project demos random map creation based on Wang Tiles. There are two sets of tiles, streets and ladders, that can be switched between. If you've ever drawn 2D map tiles before, you have probably figured most this out on your own, but I highly recommend exploring the page linked below as it vastly improved this project over my old Random Street Generator. I'll add more tile sets soon.
Thanks a ton to Locomule for creating the Random Map Generator v2!
