One Breath

An endless underwater diving game. Sink deeper and deeper on a single held breath — grab gems, snag oxygen tanks, and dodge whatever the dark is hiding.

Think Doodle Jump, flipped upside down and underwater.

What Makes It Tick

Core Features

🫧

One Breath, One Run

Your oxygen drains the whole way down. Every dive is a single held breath — bank your gems before the air runs out.

👆

Thumb-Free Steering

Touch anywhere and drag. The diver follows your finger's movement, not its position, so your hand never covers the action.

💨

Double-Tap Dash

A 1.5-second escape at 2.8× speed for 2 oxygen, on a 10-second cooldown. It does not make you invulnerable — dash to reposition, not to ram.

💥

Shatter Chains

A speed-boost pickup does grant invulnerability, and then you don't dodge hazards — you explode them. Each shatter extends the surge and speeds you up.

🌑

The Deep Gets Dark

Past 1,800 m the water closes in around your light. Hazards come faster, double up below 1,500 m, and pressure burns your air up to 1.8× quicker.

💎

Gear That Sticks

Six equipment slots, four tiers each. Spend gems on permanent upgrades, or fuse loot shards into free blueprint unlocks.

📳

Haptics & Sound

Your phone buzzes when a hazard lands. Pickups and hits have their own audio cues.

In The Water

What You're Diving For

Small Gem

1 gem. Your bread and butter — the magnet in your gloves pulls them in.

Big Gem

5 gems. Uncommon near the surface, roughly one in four down deep.

Mega Gem

50 gems. Nothing above 2,500 m, then one per 45 seconds of survival — and no magnet pull, you have to swim to it.

Oxygen Tank

Refills your air and keeps the dive going. Scarcer the deeper you get.

Speed Boost

A free surge that does make you invulnerable — your window to shatter hazards. Stacks with a dash.

Shield

Fully blocks the next hazard hit. You can bank more than one.

Slow-Mo

Eases the descent for a few seconds so you can thread a cluster.

Blueprint Shard

Loot. Five fuse into a blueprint that unlocks a gear tier for free.

The Deep

It Gets Worse On The Way Down

Difficulty ramps in five stacking ways: hazards spawn faster and start doubling up below 1,500 m, they move faster, pressure burns your oxygen up to 1.8× quicker, air tanks get scarcer, and past 1,800 m the darkness closes in around you.

New things start showing up down there too — an eel at 1,250 m, mines at 1,600 m, an anglerfish at 2,000 m. Big gems get much more common as compensation. That's the trade.

Dash engaged

Jellyfish

From the surface

Drifts and pulses its way into your line. Its tentacles sting too, not just the bell.

Barracuda

From the surface

Darts across the screen with no scroll-up warning — except the bubble telegraph that rises a beat before, in a window that tightens with depth.

Eel

Below 1,250 m

A fast riser that undulates hard side to side — the jellyfish's unpredictable cousin.

Mine

Below 1,600 m

Anchored, doesn't chase you, and hits hard. Pure punishment for a sloppy line.

Anglerfish

Below 2,000 m

The hardest-hitting thing down there — and in the dark its glowing lure is easy to mistake for a pickup. That's deliberate.

Progression

A Shop That Looks Back At You

The shop is an RPG character screen. Six slots, four tiers of five refinement levels each — and the diver in the middle actually changes as you buy them. Kitting out all six is a long haul.
