There's now a "barebones" walkthrough available online here
It doesn't look like the links in the document works when viewing it on google drive so you might need to download the file in order for it to work as intended
It does not go into any detail of what is happening at any given point in the game but rather just very briefly discusses what you need to do next in order to progress.
It's difficult not to complicate things when trying to explain a branching narrative in the linear way that a pdf document is by nature, but hopefully it's possible to follow along.
I'll try to link in an achievement guide to the document next week if time permits.
