This game suffers from heavily holding your hand all the time, even by TLoZ standards.
The infamous lid puzzle is the one that gets mentioned all the time, and the reason for that is that it's the only puzzle in the game that you don't get told the answer 5 seconds later after finding it.
There's creative usage of the Grappling Hook for example, but the game is scared of you taking too long to figure it out, and it straight up spoils the answer right after you find a torch. It also happens with the enemies that are weak to loud sounds, among other places.
The controls haven't aged very well too. Combat is fine because it's very simple, but you'll find yourself doing actions you didn't want to do, rolling when you didn't want to roll, etc. It can be a bit frustrating sometimes.
Sea travel is whatever, and the crane minigame gets a bit boring after a couple of treasures, and a bit frustrating when the jumpscare current changes start appearing (minor nitpick because you get plenty of hearts, but you still need to teleport to the first island in order to fix the Salvage Arm).
The Temple of the Ocean King actually gets more shit than it deserves. Sure, you need to go back to the isle all the time, but you need to anyway given that it's the only place where you can fix your boat / change parts / sell treasures, etc.
The temple itself enables a teleporter on your first revisit, meaning that you'll only need to replay the same part of that place once, and then once more for the second half of the temple. There's shortcuts that you can take if you got the items too, so it's not that bad.
For what I liked the most of the game, Linebeck is a cool dude, and drawing your own map on that particular isle was an interesting concept too.
