I had a great time playing this game (Wretched and Alone edition)! I did it twice back to back. The first time, my tower fell over and my character subsequently died. I decided I wanted to give it another go, so I started again in the same universe with the next wife of Bluebeard whom he married after murdering my first character. I let her find the previous wife's diary at the beginning so she had more information from the get-go. After the initial tower pull, I added a special rule where I would only pull every 3rd block that I was directed to pull. This made sense to me since my second character knew more secrets and thus her mental state wouldn't be quite as volatile as my first character's. (also, she was just a more stable person in general)
That didn't end up being much of a cheat for her, as I eventually went through the entire deck of cards anyway. I got the Ace of Hearts for her very early on, but had bad dice luck so she wasn't rescued that way. Instead, she got very lucky in the Eleventh Hour and was able to escape after setting fire to the castle and running away to the nearest village. Bonus: Bluebeard also died in the fire.
I feel that this is one of the more immersive solo TTRPGs I've played and I got so into both characters' heads that the prompts were easy to write for. I chose to ignore writing about certain prompts (while still doing the tower pulls, etc) because it didn't make sense in-character for my characters to think or worry about such things, so even with the same prompts (and same husband/backstory), the diary entries for both women read very different from each other.
It was a lot of fun and I really love how beautifully the booklet is designed! I had to print out the simple version, but I flipped through the decorative PDF for a long time before playing. I documented a bit of my playthroughs on Twitter. Here's the first wife (well, 12th) and here's the second (13th in-universe).
Thank you for a harrowing but very enjoyable couple of hours!
