Momoko 120%
百百子120%
Momoko 120% is an action game developed by Jaleco and released in 1986 for arcades. The player controls the character Momoko through side-scrolling stages, jumping and attacking enemies while collecting items for points. The game features multiple levels with increasing difficulty, colorful sprite-based graphics typical of mid-1980s arcade games, and joystick controls for movement with button inputs for jumping and attacking. Enemies spawn throughout each stage and must be defeated to progress. The percentage in the title reflects the game's difficulty scaling system.
