This is the first release of my map generator! If you want to know how to use it, please read the README that I spent the last hour writing. All feedback, feature requests, or offers of help are welcome.
Special thanks to @zuckung for sending me their mapmaking tool, and to @DarcyManoel both for their map creator and for inspiring me to do this when they asked "The big game map, was that custom made or do you have a tool for that?"
