I played this game with some friends of mine a few weeks ago! It was a beautiful little adventure, although I found that my unfamiliarity with the Kids & _____ systems was a bit of a hindrance. I think there are some rules that exist in the Kids and Bikes game that must not be in this book, and as a result we had a hard time achieving success sometimes.
When it comes to the game itself, we loved the questions about relationships with characters known and unknown. We also enjoyed the flexibility of the Tropes! (Our Witch was a cook whose familiar was a hovering cloud of spaghetti!) We had created a setting using a worldbuilding game, and used the questions provided with this playbook to set some basic themes for the world-building game.
I think it would be pretty easy to get my friends to come back to this game, as long as I read up on some ways to make it easier for the players to succeed first.
