This game feels like something in between a game and some rules for creative writing. I don't mean this in a bad way, I think it's great! But if you don't like writing, this might not be for you.
I have only played two of the provided scenarios, and it does take a good while to play each (if you play/write one chapter per night, it will take you over two weeks to play through a single scenario), but it was really fun to play and see how the story developed.
In theory the scenarios should be replayable, because you don't use all the prompts, they don't have to come in the same order, you don't know if the obstacles are going to be overcome or not, and the text of the prompts is vague enough that you could take it to mean slightly different things every time you play. But in practice I wouldn't expect you to want to play the same scenario more than twice. Possibly only once.
All in all, a pretty good solo game. And also a pretty good creative writing exercise :-)
