The section describing Flow of Play is short - if you're coming from games with a strong GM or a tighter framework of play then you might be looking for more guidance; what made this kind of play make sense to me was listening to people play, for example, belonging outside belonging games like dream askew. Once you're familiar with that there's plenty of structure here - the threat pages especially have a lot of tools for progressing the story.
I don't think I could play this safely at the moment, but ohh I want to see it played. This is a clear and beautifully written set of instructions for character creation, setup and progression of Threats. I spent way longer than I intended reading every bit of it, because every bit of it is aimed at the heart of the matter.
