Very useful per se, and provides links to even more advanced techniques to improve accessibility.
I picked up this game as part of the Solo But Not Alone 4 bundle. Once I finally got around to playing it, I really enjoyed it. The adjectives associated with the value of the cards were really the right flavor of evocative to find that happy middle ground for minimalist prompts: concise enough to provide direction, but open enough to not hem in a response.
Nice to see others work on things related to Pratchett keeping that old school fan base alive! Love it!
