Part one of my adventure map trilogy!

Some important notes:
Play in survival
No breaking blocks
There must be three players
Buttons must be placed on orange wool
Ladders must be placed on oak planks
If one player dies the others must do /kill

Also if you record a video of the map and upload it to Youtube, you must link my channel in the description of the video: https://www.youtube.com/channel/UCk6JUp87dLWL6Z7jeMKYKiQ

Do not claim that you made the map

Backstory:
The world was coming to a horrible end, and MagiTech, the most powerful organization in the world took test subjects to see if humanity could survive the coming doom. Three test subjects must complete the puzzles and work together to escape the lab. But will they?
