About this game

You are a diver lost in total darkness inside a flooded karst cave. Your headlamp lights only a small circle around you.

Tap to fire a sonar pulse that briefly reveals stalactites, stalagmites, current vents and treasure chests. The pulse needs time to recharge, so memorize the cave and plan each swipe before the echo fades.

- Swipe to swim, tap to ping your sonar
- Stalactite hits cost hearts, oxygen drains deeper
- Find sunken treasure chests for coins and bonus score
- Six working shop items: lamp skins, sonar upgrades, oxygen tank, impact helmet
- Twelve synthesized sound effects, themed dialogs, full settings
- Depth plus chests set your score; beat your best dive

How deep can you go before the cave goes silent?
