20 Ways to Die is a puzzle map where the objective in each level is to figure out a way to die. It’s an unusual way to level up but it definitely creates a unique experience. If things get too difficult there is a hint button in each level which you can use but try to refrain from using it as much as possible.

The levels consist of a good mix of redstone and other types of puzzles.
