Hi Miguel, I'm really enjoying this as a bit of mental rest in between work :)
I think a it would be interesting when there are enemies to have the option to pay them off, maybe only for a particular class, like a dwarf that starts mining and when you go to interact you can either fight or bribe? One thing I find in these types of games is if I open the cave out too much I get a bit disoriented so a way of placing markers/guides would be good. I also really like the idea mentioned below of having short lived torches. And last thing is that gold bars currently have the caption "A heavy bar of iron"
Thanks for a great game, I'm looking forward to future updates :)
