Undersea Underworld Overview
You control a diver navigating a side-scrolling ocean. Your main goal is to collect three specific treasures on each level before an exit arrow appears. Moment to moment, you're swimming around, picking up masks and skulls for points while avoiding a menagerie of sea creatures like sharks and octopuses. You also need to manage an energy meter by collecting certain items; letting it run out costs a life. The pacing is brisk, and the screen fills with hazards quickly, demanding careful movement. It feels like a constant, hectic scramble against the clock and the wildlife.
