Just started my legendary dig deep game, but am having some serious trouble going anywhere. I can not seem to find any coal in any of my caves. I found about five at the beginning but cant find anymore. Since I cant find any I cant go anywhere. I have to keep taking all my torches off the walls just to go a bit farther. Is it supposed to be this hard, or is it just unlucky caves? Also, it said there are more food sources, but I don't know what they are. Are they mushrooms, and if so do you have to cook them? Besides these things Im having a great time and can't wait for the new updates! Any help would be appreciated.
