I'm playing Oracle of Ages for the first time in a while, and it is not great! The level design is flawed. The eighth dungeon is a a dark room, some ghosts, and a hint owl that tells you to "attune your ears to the sound of sword on stone" which, right, standard Zelda fare, good of them to make explicit the reminder. But none of the walls clank! You need to push one of the non-pushable statues out of the way, in the dark, to even expose the bombable wall. I went over the whole place twice, and then thought "oh maybe they're doing a cool metapuzzle thing and I've got to leave the dungeon and bomb a new entrance" so I went out and tested the whole area with my sword and then bombed everything in case I was just misinterpreting the clank sound.
The underwater dungeon had the interesting raise/lower water level mechanic, but I explored in loops for an hour before looking up where to go next. I'm not saying it's supposed to be easy, I like a challenge, but it felt like the layout was deliberately withholding information, which is bad design.
The Long Hook is an upgrade for the Switch Hook. The improvment is marginal and the puzzles that require it feel confusing (I finally have the tool for this but it's not working (before you know about the L2 version)), forced (this is the same puzzle but the anchor object is two tiles further away) or frustrating (oh of course I was supposed to know about the offscreen anchor).
The Long Hook has an entire dungeon dedicated to it.
It seems all my fond memories are actually from Oracle of Seasons. I wonder if they had parallel teams working on them.
It's a secret to everyone!
