Thank you so much! Hahaha, I guess I wasn't clear enough in the quest log. You go back to talk to Matheo, the wizard guy, and he gives you a magic missile spell that you can use to shoot at the rocks and break up the ore.
If I had a little bit more time, I'd try and add like a compass or something to show where to go next. Maybe if I can figure it out soon I'll go ahead and add it.
I forgot to add any notification in the game, but there's also a sprint if you hold shift. Might speed up the exploration. I'll look into an auto-run though as well, that's a good idea.
