I came back after a couple months to start a new character and the first thing I noticed was being able to see what was below me on lower Z-levels, rendered with the tileset. This is great and really improves immersion, thanks again for another great QoL feature!
(Also, the new horse ranches are super cool. All the new mapgen just keeps exceeding my expectations!)
that’s already a thing though. MSXotto+ has a blue color filter for the fog
