One Breath

Dive as deep as you can
on a single breath.

Free on iPhone and Android

Your air drains every second, and the only way to keep going is to grab the bubbles drifting up from the deep. Hold to swim, drag to steer, and slip between the creatures as the water grows darker. When the air runs out, take a breath and go again.

Five ocean zones, from the Sunlit Shallows to the Hadal Trench.

Five zones,
into the dark

Sink from the sunlit shallows through the Twilight Reef, the Midnight Zone and the Abyss to the endless Hadal Trench. Each zone has its own light, its own creatures and its own music. The deeper you go, the darker it gets, until your headlamp and the glow of living things are all you can see by.

An anglerfish's glowing lure beside a real air bubble.

Not every bubble
is a bubble

Jellyfish pulse and sting. Pufferfish swell into spiny balls. Moray eels lunge from the reef walls, mines beep as you drift close, and sharks race in from the edge. And deep in the Abyss, the anglerfish waits, its glowing lure dressed up as the air you need.

A bubble combo and a near miss in the Twilight Reef.

  • Chain bubbles into combos for extra air and pearls
  • Skim past danger for a near miss

  • Hand-built hazard runs, each one with a way through
