Kaizo World PE is a fun map mixed with lots of parkour, puzzles and traps. It's inspired by Kaizo Mario World which is a modified version of the 1990 Super Mario World video game. The idea of the game modification was to break some things to make the game almost impossible to play.
Kaizo World PE has a multitude of difficult challenges where rage quit will sometimes feel as the only option. Do you consider yourself a pro at parkour? Give this map a try and you might change your mind!
There's a good mix of different challenges. Make sure to use the checkpoints (beds) whenever possible. At some stages there are chests with potions, make sure to use these to take advantage of some effect.
