Show full descriptionShow less
Drag the control to make the submarine move up and down. Most of the cave is in darkness. The player needs to actively use the Sonar pulse to briefly display the boundaries of the cave. The sonar has a cooling time and the oxygen level keeps decreasing. Collecting glowing pearls can replenish oxygen and earn points. In advanced areas, dangerous deep-sea creatures will also appear.
