If you throw the fishing line PERFECTLY you can steal his hat. You can then throw it into the lake and watch him get FURIOUS. They added so many FUN and UNIQUE NPC interactions that the world feels very IMMERSIVE.
So apparently if your TIMING is good enough you can just use an EMPTY bottle in the final boss fight. Its so funny that this works, I like when Game Devs allow the player to have FUN. More Modern Devs should learn from this.
Apparently if you SNEAK into her room in the middle of the night you can find her singing a BEAUTIFUL melody. I love that every NPC in this game has so much DEPTH. Much better than having thousands of NPC's that are empty vessels.
Every puzzle in this game is SO SATISFYING. They are CREATIVE and FUN, best of all they are easy to understand VISUALLY. No need to have a sidekick companion giving you clues every 5 seconds.
