>>16638224It's supposed to be desert grass. The tiles I'm using there are just placeholders for proper desert grass which I made by removing the grassy background from the standard grass tile and running it through a colourblind filter.
Though, I suppose I could make the desert like a cave, and have it so that if you're on any sand tile (as opposed to a dirt tile or a pathway tile), you're at risk of encountering mons.
Maybe have a constant sandstorm raging through the desert, too...
