IT WAS FUCKING AWESOME!
I did the following all with in a hour:
I mined gold, rubies, diamonds, lava, and many more not so "valuable" stuff.
I Built a sick ass spiral staircase to the bottom of the world (as deep as it would let me go) and built a sick ass house / cave system.
I killed an entire pack of wolfs (6 of them) bare handed <<the first thing i did lol
and many many more cool ass things.
this game is dope!
i collected the lave in a bucket =/
idk if that is mining
unless my buddie lied to me because he said "let me see your bucket ill get you some lave" and came back with some shit in the bucket lol
