SPINE is a solo TTRPG that looks like a book. In SPINE, you play as a researcher who has inherited this strange book from an estranged relative. You play by reading the book and following the prompts that you discover in the endnotes. But you soon discover a catch. You are being absorbed by the book — getting lost in it. The only way to lessen its power is by defacing the text.
Piece together the story without losing yourself in it.
