Simple idea for survival I guess. When someone dies, they respawn as a mob. As they do certain tasks, they can “evolve” into other mobs. Eventually, the player could evolve back into a human.
I guess the idea is that you’d have to earn your humanity when you die.
You died. You will respawn as a rabbit. Eat 20 carrots to evolve into a sheep.
(…) You're now a sheep, let someone shear you 5 times
(…) You evolved into a human, have fun playing.
