One Hit KO

One Hit KO is a single-player fighting game with two buttons, inspired by classic martial arts video games and movies. Press left to hit left or right to hit right, but a missed attack ends the run. The game focuses on skill, reflexes and concentration.

Enemies and progression

New enemy types appear as you play, making the action increasingly frantic. You face eight enemy types and a final boss. Improving your high score unlocks 24 playable characters; these are cosmetic and do not change gameplay.

Levels and power-up

The game has one long level with seven random scene changes, which are cosmetic and do not affect gameplay. A single secret power-up can help you, but your skills and reflexes are what matter. The game also includes references to 1980s and 1990s martial arts.
