Challenge from Kiyoshi

Life seems to be going good. You're doing great at your job, and the company's fortunes are on the rise! But just as the president invites you into his office to name you as his successor, a massive earthquake shakes the city, tearing it asunder and reducing the world around you to rubble. It's now survival of the fittest, can you escape with your life?

Challenge from Kiyoshi (Kiyoshi no Chōsenjō) is a fan-made sequel to the infamous Takeshi no Chōsenjō, released as part of an elaborate April Fool's Day joke in 2010 which presented the game as a lost sequel, designed by the straight-man comedian "Meat Kiyoshi" but never released as the game's content was deemed too disturbing and unhinged.

The game is a high-difficulty action platformer designed to trick the player in the style of "Kaizo Mario" ROM hacks which were popular at the time, with nearly every jump or platform hiding a trap of some kind. The player can jump, duck to high jump, and attack with a short melee combo, and is given a thousand lives to complete the game, with progress saved after clearing each room. The game includes four different endings depending on which secrets the player finds throughout the game.
