Update: I’m on Dungeon 5. I was getting my ass kicked by Darknuts (all time great video game enemy name), then realized that I needed to explore the overworld more. So glad I did. Secrets everywhere. Did you guys know that you have to bomb EVERYWHERE in this game?
I feel like I unlearned 30 years of game design today, and it was exhilarating. I've been trained to believe that every secret in a game is CLUED somehow. Instead, it never stops being shocking how many UN-clued secrets there are in LoZ. You just have to look for walls that COULD have an opening in them, and bomb them. I always thought this would be frustrating, but it's actually enormously freeing - secrets could be and ARE everywhere, right under your feet!
