I played it as a kid, though to be fair the only progress was made when my dad played. It was mostly brute force, “ok, can’t go any further here let’s try another path.” And eventually you were at the final boss. My dad eventually got to the end and thought he got lucky, that he’d just happened to go through the rest of the game first and collected everything he needed. I don’t actually think it’s possible to get to Ganon in the first game without going through all the dungeons.
