One Breath
v1.5.1Touch anywhere and drag to swim. Sink deeper and deeper on a single held breath — grab gems, snag oxygen tanks, dodge six hazards, and bank your haul before the air runs out.
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 an 8-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, and the descent keeps accelerating — but the field stops getting busier at 6,000 m, so the deep is survivable rather than a wall.
Gear That Sticks
Six equipment slots, four tiers each. Spend gems on permanent upgrades, or fuse loot shards into free blueprint unlocks.
Twelve Abilities
Past the gear ceiling, a second progression. Equip one — eventually three. They trade rather than buff, changing what a dive is rather than making you stronger.

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 stacking ways: hazards move faster, air tanks get scarcer, and past 1,800 m the darkness closes in around your light.
As of 1.5.0 it stops ramping forever. Hazard density levels off at 6,000 m, and the field can no longer seal shut — if there is no clear place for a hazard to enter, it simply doesn't spawn. The deep is survivable now rather than a wall you halt at.
New things still start showing up down there — an eel at 1,250 m, mines at 1,600 m, an anglerfish at 3,000 m, and vent chimneys in the trench at 9,000 m. Big gems get much more common as compensation. That's the trade.
Dash engaged
Jellyfish
From the surfaceDrifts and pulses its way into your line. Its tentacles sting too, not just the bell.

Barracuda
From the surfaceDarts 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 mA fast riser that undulates hard side to side — the jellyfish's unpredictable cousin.

Mine
Below 1,600 mAnchored, doesn't chase you, and hits hard. Pure punishment for a sloppy line.

Anglerfish
Below 3,000 mThe hardest-hitting thing down there — and in the dark its glowing lure is easy to mistake for a pickup. That's deliberate.

Vent Chimney
Below 9,000 mHydrothermal towers in the trench. They don't move, and there is no way around one that isn't through the gap beside it.
The Descent
Seven Zones Down
01
Sunlight
Light still reaches down here.
02
Twilight
The last of the blue.
03
Midnight
No sunlight has ever been this deep.
04
The Abyss
Things that never came back up.
05
Hadal Trench
Where the seafloor gives out.
06
The Chasm
Deeper than any ocean on Earth.
07
Below the Chart
Nobody has measured this.
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.

Tier I
Basic

Tier II
Steel

Tier III
Titanium

Tier IV
Abyssal
Dive Helmet
A brighter beam — the deep dark closes in less.
Speed Fins
Dive faster — reach greater depths per breath.
Oxygen Tank
Start with more air, and refill more from each tank.
Dive Suit
Hazards cost you less oxygen.
Grip Gloves
Pull in gems from farther away.
Lucky Charm
Every gem you grab is worth a little more.
