In miner mode you spawn in a cavern underground. It's all about finding ore . You can go to the surface but for every 5 seconds your up there you lose half a heart. There are special oasis like places in the ground where you can get wood and plants and build a house. Torches give off light in your hand. You also start with a crafting station, 1 stone pickaxe and a torch to see what you are doing. It would be good for people who like to just mine and build underground it would be a world option like superflat or large biomes so it's completely optional.
What's up? I'm the proud co-owner of a little ClassiCube server called Minebuild.

Sometimes, you just need a little more cave.
