I had a hard time with this one. It's a great atmosphere (especially love the fabric style trees and dinosaurs) but paired with VR it was hard for me to enjoy since it's a lot of being lost in the forest with a lot of assets that all look the same. I thought it was going to be you go through the manual in sequence but it ended up being you just discover all the elements randomly, and when I finished, I'm not sure I even got all the pages.
Initially I tried playing it co-op, but I don't think the second player could offer much advice. Unlike Keep Talking where the second player is constantly required to cross-reference clues for the VR player, in this all you can really do is keep encouraging them to explore and give them vague suggestions of what to look for (and again, the non-linear nature makes it hard because you have no idea what the next thing is they might stumble upon).
