Keep in mind that this review is from someone who has only read the book, not actually played the game.
While I see a lot of ideas in this game that I really like (the cycle of Themes and their extreme ends, the use of tags to produce Power rather than stats, a really interesting setting), I feel like in a some ways it doesn't quite hit the mark. I think it overcomplicates the PbtA style a little too much and the setting didn't always feel entirely consistent with itself. The layout of the chapters is a little strange as well. It starts with a description of the setting, then goes into character creation, then the mechanics of the game. There were certain points in the first chapter and especially in the second chapter where I was pretty lost in the terms the book was throwing around. Having read and played many other PbtA games, I had some pretty good educated guesses about some that turned out to be correct, but there were others that left me completely in the fog (baddum-tsch) until I reached the relevant entry in the third chapter. I would recommend reading chapter three and then going back to character creation.
Would have given it a 3.5 if that was an option. There are definitely more good things than questionable ones and I'd be interested in seeing how a lot of the decisions actually translated into play.
