Welcome to my very first project I'm uploading at PMC.
The purpose of this map is to survive in a cave without getting to the surface.

You (hopefuly) spawn on a small floating island with dirt, stone, a tree, a chest with some goodies, a bed and your challenges written on the signs.

The challenges are the following:

Find 10 chests with a diamond in it: Within the cave, you will find several chests. Some may contain seeds, others will contain a diamond. It's your job to find the 10 chests and bring the 10 diamonds safely back to your spawn point.

Find seeds and make a farm: As sais before, some chests wil contain seeds. Find them and make a wheat, pumpkin, melon and sugar farm.

Reach the torch at the top of the cave: You'll notice that there is one torch at the ceiling. It's your job to reach that torch.

Find the hole that leads to the oblivion: When playing this map in survival mode, it's impossible to break the bedrock. But there is one spot that you can break. Find that spot.

Find a mineshaft: In one of the many sidecaves, you will inmediatly find a mineshaft. Locate it and explore it.

Those are the main challenges, you can set up some for yourself as well :)
