Just tried sequence breaking by only freeing one giant. (you need one to learn Oath to Order, of course) Turns out you *can* play the Oath to Order and *can* get the giant to come, but the moon doesn't stop. Will try with two and three giants and see if that works.
lol, not only did the bad ending not finish, but for some reason Project64 gave an exception error...
I have found something that may speed up the water hopping portions as a Deku Scrub though (if there are any left with new TAS runs): Spinning off the ledge causes you to hop forward at the same speed you spun with. (sorta like the shield/bomb trick only forward instead) I'm sure it's been noticed before, but just in case it hasn't...
And looking at the SDA video, I see a good few minutes of improvement that are just due to human error... I could easily see this end up at close to 1:45 if not 1:30 TAS'ed...
