Pokémon Blue Kaizo (2014)

Pokémon Blue Kaizo is a ridiculously difficult ROM hack of Pokémon Blue which, as the title implies, was inspired by the like of Platform Hell hacks such as Kaizo Mario World. Everything about the game, including the wild Pokémon, the teams of trainers and gym leaders, and even the layouts, has been changed to make the game a much more difficult experience.
