The Winged King of puppets, frost magic ballerina Old Bones, the characters this game inspires are some of the most memorable of any ttrpg for me. A trick I love is to have each player bring their own oracle deck. To have multiple materials woven through the play.
Also, I love the sense of hopeful sadness this game carries. My playthroughs really stick with me because of how they went into painful feelings in a way that was constructive and positive.
