Thank you it really is "how to write a book from scratch" and when I went to playtest it, I was like oh no this is probably not right for a journaling game 😅
When I playtested it without the appendix, it felt like if you didn't know anything about improv or writing your own stories, the prompts would leave you very little to work with. So then I added a bunch of story structure stuff I knew, but I realized once I playtested that version that now it was too complicated 😅
So I'll have to keep a look out and test other people's solo TTRPG games more going forward if I want to make stuff in this genre.
