Absolutely fantastic! Did a short session last night, and within the first two tiles I was already well on my way to exploring this little world. The feature table and descriptive words are a perfect balance of specificity, while being vague enough for interpretation. I'd personally would have liked a way to generate the descriptors through rolls rather than it being a consumable list, but that's also considering I played solo and I'm bad at making decisions on my own hehe.
Works great as an artistic excercise too; would love to organize something with pals to collaborate over a Drawpile type server sometime.
