Nchardak has to be THE one and only level in any video game I've ever played with a water-level mechanic that didn't make everything hideously annoying. I've played three Zelda titles with incredibly annoying/tedious water puzzles, and when I went into Nchardak for the first time, I was like "oh god no, not one of these". But...it's not annoying! It doesn't make me want to throw my mouse/laptop into the nearest wall!
