I fricking love generated art, which i made a whole tool to draw my stupid doodles and get cool stuff out of it lol. This looks super cool though, in the limited design space it occupies it's gorgeous. Love the generators.
I've been adding to it and trying to figure out how exactly to use it best but I really like it, stuff like this deep-fold really inspires me to do more with it in various ways (: One big thing I'm planning on doing and haven't had time for quite yet is shaded heights, so like, give the program a color and shades of that color and have it basically block in areas of terrain with a simple few pixels shade "under" those areas to give it that classic pixel verticality in little cobbles or paths. This example is a lovely piece by Frannek on twitter, goat of pixel art hehe. But you see the color mapping there.
