Had an excellent time with this as a solo journaling experience. A tweak for solo I used is to insert the Ace of Spades 1/4 of the way from the top of the deck. This still developed the story well, especially since I was the only player, and probably increases replayability even more.
Some notes on my session: the story developed wonderfully with a full-fledged arc and a sense of growing unease as the secrets of the wizard and the tower are uncovered. Your character's backstory develops on the fly, leading to a final catharsis.
This is an extremely satisfying storytelling game I'll keep returning to. An absolute gem.
