It's very pretty and the climbing/exploration is enough to get started with mechanically, but I felt underwhelmed overall. I think the complexity of the climbing situations didn't progress enough. A common thing in rock climbing is reaching an awkward spot and having to retrace your steps a bit before moving forward in a different direction, and they surprisingly never do anything like this. you rarely even traverse something that isn't entirely linear. Which would be fine if other aspects were more interesting such as the story, but personally outside the well-executed world building aspects I didn't find much to care about.
