kgoerner's floating island

This is another survival map again.

This time you're on a floating island in the sky (there's no void. I did that on purpose).

Rules:
Do not touch dry land.
If you die before you slept in the bed, switch to creative mode to get back to the island.

Achievements:
Find a diamond.
Find the secret room.
Make a farm.
Enchant a weapon or tool.
Go to the nether.
Make a potion.
Go to the end and defeat the ender dragon.
Optional: defeat the wither.
