Jankenman

Jankenman is a side-scrolling platformer on Game Boy based on the anime series. Players control Jankenman, a masked hero, through levels to rescue kidnapped friends from the villain Masked Osodashi. Gameplay involves running, jumping, and collecting items, with health tied to a timer. A key mechanic is a janken minigame at the end of levels, where players choose rock, scissors, or paper to defeat the boss and advance. No specific named friends or characters beyond the heroes and Masked Osodashi. What makes it stand out is the unique blend of platforming with rock-paper-scissors combat, tying directly into the anime's theme for a memorable and short play session.
