Oh gosh yes I know it's the edge of the map. What I don't know is why you'd design the game so that a part of the mainland is out of bounds. I'm literally ON the wall it's telling me I can't climb. Just make any part of the game that can't be explored endless ocean.
It's annoying because I'm running around exploring, running towards a mountain I'm excited to see and then suddenly I hit a border.
Well you are already aware that's an edge first of all. And maybe they made it that way so that the entirety of Hyrule is not just a one giant island disconnected to the rest of the world.
