Absolutely love the open world and how the gameplay has a perfect balance between complexity and streamlining, abstracting real-world survival concepts just right.
Unfortunately you need to spend a huge portion of your playthrough mucking about in shrines to ensure you aren't getting one-shotted in later areas. They have some great puzzles in there, but the lack of variety in visuals and sound (I believe there is only one song for all the shrines) make the jarring disconnect between the over & underworld even worse. The 'dungeons' have this same issue, too.
Still, I can understand the immense extra work it would have taken to implement all this variety and the actual gameplay is good enough that it's not too distracting. I just wish more of the puzzles were integrated into the overworld - they already do this at points, just not enough IMO.
Absolutely gorgeous game, though. The rolling hills and valleys and the way the light bounces off the grass will never leave my memory.
