Hyrule Castle is one of the largest stages in the game. There are three different main platform sections, so I'll go by one at a time. On the left side is a simple platform which is slightly slanted downwards to the left. And that's it. Nothing else is over there. In the middle is the main stage, which is just flat. There are three floating platforms above this part of the stage. Two are placed in the same spot at different elevations, and one is to the right, with the elevation in between the other two. The platforms are kind of in the shape of a greater than sign. On the right is another main platform with a lower elevation. On this platform there is a tower with a solid top and an opening at the bottom, which players can walk through.
