MCPE. I'm playing a map I found on MCPEDL called LuckyTree SkyBlock
I got loads done so far

A cobble stone generator (put a slab over the lava so I don't fall in

A small tree farm
Found two of the other island islands

The item frame gives unlimited iron pickaxes and the lucky blocks actually does stuff when broken. It almost killed my ones. One time I said " I need food lucky blocks" and broke one it gave me food but it fell of the island... I need to expand the island...
