I'm done with the Water Temple. The buildup to it was great, especially that Ancient Zora Waterworks with the amazing music. The Ruta reworked track of the Water Temple was among the best in the game.
The Water Temple is fairly small, but two puzzles got me scratching my head. The boss was super fun though, and I love the water mechanics. Made myself two Opal rods, an Hydrant shield and stacked loads of Splash fruits.
What I like about the game is how all the secondary characters have a journey within the game, and how much they've changed and evolved from BotW. Sidon clearly carry trauma from losing Mipha and it showed throughout the Zora sequence.
