Currently going through the shrines to finally get my two full rows of hearts.
I'd love to hunt for kook seeds but since the reward is a literal steaming pile of crap, I don't think I'm going to bother lol.
Same thing here in regards to shrines.
I've beaten the main story however I really want to take the time and visit all of the shrines, find as many Korok seeds as possible and work on getting the armor pieces.
It's crazy how fast time flies in this game, inside it, and real life time.
