I had a really hard time solving the water puzzle.
Spoiler:After having struggled for hours I had to check a hint and discovered I was supposed to hear different sounds by the water fountain, opposite of the flute. I only have the background music at that location. After having downloaded a patch with subtitles I managed to solve it since I got subtitles for the sounds of the fountain. I didn't find any patch to get me the actual sounds though
All and all that puzzle was a really fun challenge. Now I only have the last element left. That'll be tomorrow.
