Unbreakable Master Sword and Hylian Shield, full Link costume, and
actual dungeons with actual (stupidly simple) puzzles.
Solving the dungeons - I say dungeons but I actually mean secret libraries, abandoned mines, forests, caves, temples, and occasionally
an actual dungeon - usually involved spacial puzzles, managing to collect a new item that allowed you to interact with the environment in a new way, and MORE spacial puzzles based around your new ability.
Furthermore, you are never setting up
an actual dungeon.
Because if Neogaf is anything to go by, they already have an idea of what
the actual dungeons may be like.
The actual dungeon - crawling gameplay is hardly extraordinary, but the 60 second - long lives the game gives you elevates it to a fresh curiosity.
There isn't
an actual dungeon because the whole world is pretty much one surrounded with enemies who were under the influence of the Ostinato Musicians and µ music.
Namely,
the actual dungeons you explore throughout the story.
Notably, the overworld (which underwent several alterations as well) is explored akin to the dungeons, as Link has to make use of his tools and skills to make his way through the areas, as well as to meet the various conditions and items to gain access to
the actual dungeons.
Now
the actual dungeon crawling involves differently styled labyrinths that are randomly generated.
During
the actual dungeon crawling sections, you take a team of four into the fray in order to complete quests, kill enemies and defeat bosses.
The actual dungeons are pretty wide open, brightly lit for the most part, and visually appealing on a 3Dfx.
