I've been looking at how you structured the save file persistence across sessions—that's the hard part most solo tools skip. Forcing the GM to actually maintain state instead of just generating random encounters is clever.
I'm building SagaForge: a platform that plays TTRPGs directly from their rules. You paste in your system, name a character, and start playing. The engine tracks everything—character sheet, world events, inventory—without you having to wrangle markdown prompts or manage chat sessions manually.
I think Cairn would be a strong fit. We're offering free integration for 10 designers, plus we'd run a full public replay of your game that anyone can read and follow along with. Your name stays in the credits.
The core question: would you want your game running on a platform where people can actually just *play* it without setup, instead of copying your prompt into ChatGPT?
