Sea Diver

Sea Diver was one of those straightforward games you'd find during the Flash era, a time when a simple concept and a few minutes of your attention were often enough. It didn't try to be more than it was, which was a familiar kind of browser-based diversion.

You control a diver descending into the ocean. Your mouse guides them left and right, avoiding jellyfish and other hazards while you collect scattered coins and treasure chests. The main goal is to gather as much treasure as you can before your oxygen runs out, which adds a constant pressure. The pace is steady, and the difficulty comes from managing your air supply while navigating the increasingly busy lanes of sea life. It feels like a quiet, focused race against a slowly emptying tank.
