Jankenman — About this game
Jankenman turns a rescue into a race against the clock. Choose among four opening stages, climb ropes and jump over traps to reach the masked villain holding a friend. Touching a nuisance does not kill Jankenman, but freezes him while precious time drains away. Optional rock-paper-scissors rooms can give useful items, while the showdown needs five winning stars and a loss removes one. Success therefore depends on reaching the duel with enough time left to finish it.
Use SELECT on the stage screen and START to choose. Left/right move, up/down climb ropes and either A or B jumps. At a duel, up/down picks a hand and A commits at the signal. Save time before entering optional rooms; their clock keeps running too.
