Compass will be cool
I have to decide, Minecraft or Civ V now!
EDIT:
Yay, sound works again on minecraft. And I just found a monster spawner and 2 chests in a dungeon. Some cool loot stuff in there.
Edit 2:
I think a spawn tunnel will be a good idea. Ive sunk another mine shaft, found craploads of iron, coal and some gold, but its swarming down there, nearly dead, so a quick safe access is needed as I forsee losing a lot of materials otherwise!
