If you fall you die. It is very simple.

You start with pistons and Redstone because they might be helpful.

Every time you fall you die!

You will not die if you are in creative or spectator mode though. (It says some really annoying messages if you fall and you are in one of those game modes)

You can prevent all of this by being popped or having the permission "falltodie.immune"

Thank you to Kyllian for giving me the idea.
