I haven't! This is my first time hearing of this book :o Why do you ask?
It's absurd that I finished it and immediately after, without any correlation, I played your game! Perhaps that's why I found so many references and connections: the relationship between psyche and flesh, plants and human relationships... I recommend it to you; I think you'd find it stimulating! Kudos again!
Upon further inspection (admittedly I glanced at it briefly as it was just linked from a Pin on Pinterest), it's actually appears to be a digital print taking inspiration from The Vegetarian with some interesting text.. I saved lots of meat pictures for inspiration. I still think it's worth looking at and reading. I would buy if it isn't wasn't $1300 haha. Here is the link
