When I was planning the Zinequest Kickstarter for this game 2 years ago (gosh), I added a Box of Leaves tier that entitled the highest level backer to a copy of the game handwritten on dried leaves. But I didn't really expect anyone to claim it!
However, someone did and then that someone was very patient with me while I collected and dried 204 leaves.
So now this is a thing that exists in the world.
To my knowledge, there has never been another zine that has been released on leaves.
