First look
Five biomes
From the sunlit Shallows down to the near-black Abyss. Every dive is a fresh cave, carved the moment you drop in.
The Shallows 
Kelp Forest 
The Deep Blue 
Sunken Ruins 
The Abyss
How it plays
Four systems, one dive
A short list of ideas, each tuned until it earns its place.
Air, not a timer
Your air is the only survival constraint. Reach the exit before your air runs out, topping up at air pockets on the way down.
Procedural caves
Every dive is a fresh cave, carved the moment you drop in, so no two descents through a biome play out the same way.
Five biomes
Twenty levels descend through five biomes, from the sunlit Shallows to the near-black Abyss, calm up top and quietly tense the deeper you fall.
A boss at each deep boundary
Past the sunlit Shallows, every biome is capped by a boss at its boundary, marking the line between one stretch of the descent and the next.
About the game
One breath at a time
Kyle dives a freshly-generated cave each level, where yourair is the only survival constraint: reach the exit before your air runs out, topping up at air pockets on the way down. Accessible and relaxing on the surface, quietly tense the deeper you go.
Twenty levels span five biomes, from the sunlit Shallows to the near-black Abyss, each one past the Shallows capped by a boss at its boundary.
Built by a dad and his two sons, and forgiving on purpose.
Some caves hold more than pearls. What the deep is hiding is yours to find.
