This might have already been suggested or is WIP, but shoudlnt rivers be more “random” and not so square-ish? To me right now its one of the worst parts of the map gen, I’m not sure if it is juts very hard or is supposed to be like that but it looks really bad to me.
If you’ve a better implementation, by all means PR it! Actual riverbanks are pretty decent IMO, but mapgen can sometimes serve up Interesting courses.
