--Structure--
This is the first dungeon since Tower 2 to force backtracking. In Tower 2, you only had to backtrack one floor right at the beginning, but here, you get nested backtracking across multiple floors.
It's got two points of backtracking. First, you go all the way to floor B6 (Giant Leaves), which is a dead end. From here, you backtrack to floor B4 1, where you can now access floor B5 (to Ra Dewdrop). That passage is not a dead end; it loops to floor B3, which takes you close to the second point of backtracking, the boss door in floor B2 (north half).
It's also worth noting that floor B2 offers two methods of backtracking. Coming from the south, no matter what you have, you can always do the block pushing puzzle to get to the north half. Or, if you have the Giant Leaves, you can swim across the gap.
What's interesting is that the first point of backtracking is forced, but the second isn't. There's no way to get to floor B6 (Giant Leaves) without passing through floor B4 1, which itself has the door to floor B5 (to Ra Dewdrop). In other words, on your way to the Giant Leaves, you pass very close to the passage to the Ra Dewdrop. However, on your way to the Giant Leaves, you are not forced to pass near Parasite's room. If you don't explore floor B2 (north half)--which is possible, it's totally missable--you'll be missing out on the Ra Spear for most of the dungeon, and you might have a hard time spotting the boss door later on. On the other hand, you'll be saving yourself time, since it's not necessary to explore floor B2 (north half) until you have the Ra Dewdrop.
