About 23 hours into it and I feel I've only scratched the surface. There is still a massive portion of the map I haven't even visited yet. I absolutely love the exploration aspect of it. I hate cooking in real life, but I actually enjoy it in game. I enjoy trying out different combinations, but I refuse to use any guides yet. I don't mind the fact that weapons break, but I wish they lasted a little longer. I've tamed two horses, but I find that I really don't want to ride them when I'm exploring. I'm upgrading my heart twice for each increase in stamina because I've ran into very few places that I couldn't climb up to.
Spoiler (sort of):
Check out the island at the south east corner of the map. There is a really fun trial that awaits you on the island. It took me two nights to finish it, but it was really fun.
Another spoiler:
My best advice is to upgrade your bombs as soon as you can. The faster regeneration makes a lot of difference.
