This is beautiful. Every stage (the introduction, every chapter and the prompts) adds depth to the atmosphere and evocates a precise moment and mood for you to write about.
I love the concept of reutilizing a game as another with whole new mechanics and vibes, as I have been playing around the idea of making a narrative game using Quirkle. I didn't know about 7-Families before and you're making such a good use of the categories the card game already has that it blew my mind!
Rest assured your explanation is clear as I understood what to do at every step. I'll be definitely playing it soon.
