According to a update from June 2017 on Kickstarter: "The document will be made available exclusively to all backers free to download as a printer-friendly PDF." From that, it sounds like it's not going to be available elsewhere. However, that information is over a year old now, and things could have changed since then. I don't remember seeing anything more recent about what the availability of The Long Way Home would be though, so we might have to wait for more info from the creator on this to be sure.
Thank you for the reply. That is kind of disappointing to me.
