[Puzzle Map] The Pit

Hi there everybody! This is a minecraft mini puzzle map which will test your imagination skills.
You start in a pit, you have some limited resources in your hands and you have to find a way out of the pit alive. There are no mob challenges involved, just plain imagination.

The goal is to figure out how to get out, it may seem impossible, but I assure you it can be done.
Everything in the room is useful. I am 99% sure there is only one possible way to get out, if you find more, feel free to let me know.

You have only one life, so use it well. If you die then it's game over, you'll have to manually reinstall the map to play again.

One more thing, you can destroy, place and craft whichever items you need to get out, use your resources carefully.

Objective:
-Get out of the pit alive.

Rules:
-No mods that alter gameplay.
-No cheats (obviously).
-Play on any difficulty you like, there's no difference.
