This is basically Firewatch in space, this one is great especially cause of it's setting and atmosphere. I loved both of those things and kinda want to read the book now just to see what the cannon choices were for Yasna. If you don't mind a walking simulator this game is fantastic, you can truly get immersed in it's world.

As for the game polish itself, you can obviously tell that it's indie and not super polished BUT... it's still incredible. I really hope there's more of this world in the novel that I can discover.

EDIT: OMG THE GAME IS A PREQUEL TO THE BOOK, THE GAME FLOWS PERFECTLY INTO THE BOOK, I'M LOSING MY MIND
