Heh, I got it completely wrong and got stuck at the top of a mountain at night - instead of tunnelling, I carefully fortified the mountain top... well, ok, I ran around in circles spamming torches and punching creepers in the face screaming 'why?!', but by sunrise that mountain-top was encircled by a 2 block high wall of dirt and covered in feathers and bones from the dead. That was a good first nightoplinger said:A hole. I'm sure i'm not alone in this. It's quick...takes no time...and when you didn't know what the hell you were doing, about all you could handle.
Look straight down, dig frantically as the moon comes up, place a block above you, and pray to god there are no spiders...
