"Great procedure to write and play gamebooks-style narrative on the go. Since you participate to several stories in parallel, there is no downtime, and a good chance that connections start emerging to generate a larger picture. I have to say that the visual could have a bit more attention, but it is very functional.
You could easily add more players, with various rules framing the swapping of stories. What if you have several characters and, depending on which one the choices focus on, you hand it to a specific player? You could also add randomness into the mix with multiple outcomes per choice. A last idea that comes to mind is to apply it to lore instead of a narrative arc, defining the background collaboratively before playing in it."
I wrote this review in my selection of 12-word RPG where your game is featured by the way.
