The goal is to survive. And to do that, you'll have to find the items you need to survive! There's plenty of wood, coal and dirt to make a nice and safe home. Post screenshots of your skygrid world in the commends!
The lava burns and falls down creating a glitch of ashes and burning my house down can you fix it
It's a bug in PE, which is really annoying. Try the seed nyan, and walk towards to the lava. If you wait a little longer, the whole map will be on fire! It will probably be fixed in the next update (fix it Aron!). I could remove the lava, however you don't have infinite cobblestone that way... I'll see what I can do (maybe move the lava to a save place, or make a already build cobblestone generator), I will update it tomorrow.
