abyssal theft

Sonar
Leviathan.

The cave is black until you ping it. Sound is a flashlight that also tells the animal where you are. Steal three relics. Surface. Do not become a story.

The hatch is shut. Descend, then press Space to reveal the cave.

• WASD / arrows thrust
• Space ping
• R surface

Search east for gold relics. Cyan marks your hatch; return there with all three. Best successful dive stays saved.
