Drownlight

Drownlight is an underwater (beneath the surface) adventure game where you play as a lost pirate diver descending into the unknown. Fight through treacherous reefs, collect sunken treasure from a crumbling shipwreck, and face the kraken lurking in the deep trench below. Every second underwater drains your oxygen, and one wrong move means starting over. How deep can you go before the ocean swallows you whole?
