On the plane ride back from Miami yesterday, I decided to finally give Ganon that work
I didn't hit every room in the castle being that I already was running through the castle earlier. I left to go get the final memory and the blood moon occurred
I wasn't about to go through killing all the enemies again... I entered the castle from behind and used Revali's Gale to get to the top.
The battle wasn't that bad until Ganon turned into fire and it took me 30 minutes to realize I had to do the perfect dodges/flurry rushes to inflict any damage
. I suck at dodging and haven't really needed it at any point in the game, so it took a couple tries to get the timing down. After that it was a breeze.
Might go back and finish all shrines one day but it might be on to the next game now.
Game was GOAT Zelda status
