This next course was a very ambitious one. I present, the infamous Water Temple from Ocarina of Time!
Code: FC1D-0000-00B0-62C9
A very, very difficult course. One mistake could cost you a lot of time, and there is not enough time to backtrack (if only the max time limit could be increased over 500). Each power-up (Super Mushroom, Fire Flower, Cape, Yoshi, Star) act as your keys to open up the next area, eventually bringing you to the end of the temple. Navi is also featured in my Miiverse comments throughout the course to help guide you through the course.
And of course, like the old N64 classics, there are some "exploits", if you can figure them out...
