A no damage run is a self-imposed challenge where you play through a game without taking any hits, forcing you to learn enemy patterns, timing, and level layouts intimately. It's a test of precision and patience, often requiring dozens of attempts to perfectly dodge every attack, jump over every hazard, and clear bosses without scratching your health bar. The reward is the satisfaction of mastering the game to its absolute limits.
