I am an average player in terms of speed. Not too slow, not too fast. I see that most players get to the Water Temple at about 12 hours. Well, I'm at almost 22 and still didn't see or hear its name. I am not so slow where I didn't get to it yet. I Just collected the tears of light for the third time (first was in a forest, second set was in Kakariko Villiage, and the set I just collected was over a lake, in a castle and all over). I am now in human form again. I have beaten the Forest Temple long ago, and the Goron Mines about 10 hours or more ago. I am now around Lake Hylia. Is the Water Temple a side quest that I may have missed?
