A very interesting game that nearly overstays its welcome. The core gameplay loop isn't much more than "go up, then go down, then go up" again and again, but the alien landscapes coupled with a few interesting mechanical shifts (wind, water, etc.) switch things up enough to not feel stale.

The story is there, but it's told in a way that seems a bit more obtuse than it needed to be. There's a satisfying ending here, but it'll land flat if you haven't pieced together the narrative bits along the way.
