use the pegasus boots
That's so weird because in the original version you can just use your spin move (if I remember correctly...). Apparently I tried every item on the Ganon form EXCEPT the pegasus boots. Now I've tried the boots, and managed to beat the game. Thank you! This version of the game is truly amazing. I played it zoomed waaaay out a lot, and realized that it's so much easier when you can view the entire map in real time.
