It's beautiful. But also pretty unsatisfying in a way. Roads don't make sense. Rivers barely make sense. There's no higher-scale structure - the reason why most games with incremental procedural generation usually feel stale after a while, and always static. Every planet is different, yet feels the same. (Dwarf Fortress is the one procedural game I know - besides maybe its more faithful clones - which isn't static. B…
Noita is also procedural, but not static, although I'm not sure if that's what you're talking about.
Noita uses herringbone wang tiles where each wang tile pixel is 16x16 simulated in-game CA pixels, with tiles selected from a per-biome pool and the ability for biome-specific scripts to override certain areas too. As part of expanding each wang tile pixel into 16x16 pixels, some noise is applied to terrain to add the curvy look, with another layer of (thresholded perlin?) noise that controls which bits of inner terrain get variations (gold veins etc).
Source: working on a Noita-like so have spent a bit of time looking at prior art. Noita wiki.gg will explain a lot of it though (warning: many spoilers).
