Play Kerateka Online
You’re a karate fighter moving through a castle, trading precise punches with guards—one mistimed move sends you back to the start. The animations still feel slick, even after all these years.

Kerateka was released for the Nintendo Entertainment System, though I don't recall the developer or publisher offhand. It's one of those early NES titles that feels very much of its time, a straightforward action game without much fanfare, relying on simple mechanics and a clear, punishing goal.
You control a lone karateka navigating a multi-level castle, screen by screen, to rescue a kidnapped princess. The core of the game is its timing-based combat; you trade precise punches and kicks with guards, and a single mistimed move means starting the entire level over. The stiff, deliberate pacing makes every encounter tense, and the lack of continues reinforces that tension. It feels like a test of patience and rhythm more than a brawler.
