Syobon Action

Syobon Action, or Cat Mario, is a Japanese flash game created as a parody of Super Mario Brothers. It is usually called 'Cat Mario' because instead of a plumber, you play as a white kitten (former japanese emoticon). The game is known for its harsh hidden traps like invisible blocks, invincible enemies and falling platforms, which are scattered throughout all four levels. The game is ridiculously hard, and Liam Tullett and Michael Rehfisch are known to be the only people who have completed it, with about -280 lives.
