I've been playing Minecraft for a couple months now. I've certainly discovered that I really am most interested in digging and amassing a bunch of raw material for building mega-complexes. Furthermore, I don't mind killing and hunting mobs except when I need to but that's not why I play the game.
I started my first level on the most difficult setting of MC. The problem that I have run into is I have dug a HUGE hole straight to black stone and have expanded my mine from the bottom layer. I hit a sizable cavern with tons of Iron, Diamond, Red Stone, etc.-- everything that you would want. Since I maxed out the difficulty of the game, I keep getting killed as soon as I turn my back away from the massive hole and toward the goodies in the ground because there are so many friggin mobs in their.
Is there away that I can modify my current save state to set it to the easiest difficulty level with mobs? I've done a lot of work on this level and I'd rather not have to start all over again but I'm afraid that is what I will need to do. My torches (which I tried to place everywhere that I can reach) aren't keeping the mobs away.
