About This Game

A breathtaking adventure.

Kyle pulls on a wetsuit, checks his tank, and slips beneath the surface. Below him a whole ocean breathes: kelp swaying in the current, shoals scattering as he glides through, light falling in shafts from far above. Every dive is a new cave, drawn fresh, and the only clock is the air on his back.

Kyle Coral is a cave-diving adventure built around that one idea. No countdown, no score to chase. Read the cave, find the air pockets, and reach the exit before the tank runs dry. Pearls prised from clams buy permanent gear at the Trading Post between biomes: a knife, a harpoon, a scuba tank, a dive light. What you buy, you keep. You descend from the sunlit Shallows to a bioluminescent Abyss, with four guardians waiting in the dark.

Forgiving by design, and playtested by the developer's two kids.

A living, hand-made sea

Every wall, creature and beam of light is drawn procedurally. No two dives look the same, and the world reacts to you: shoals scatter as you pass, light shifts as you descend.

Air is the only clock

Nothing ticks on screen. The tension is a held breath, not a countdown. Read the cave, find the air, surface alive.

Five biomes, four guardians

Descend from the sunlit Shallows through the swaying Kelp Forest, the open Deep Blue, the drowned Sunken Ruins, and the bioluminescent Abyss. Each biome has its own guardian waiting in the dark.

Gear you keep

Pearls buy permanent equipment at the Trading Post between biomes. Everything you buy, you keep, and missing gear makes a dive harder, never impossible.

Forgiving by design

Kid-tested, full controller support, a colorblind aid, and an opt-in Assist Mode. The pressure is real without being cruel.
