Take what you can carry. Reach the bell before your air runs out.

What it is

You drop onto a wreck with a finite amount of air. Everything worth having is down there, and every second spent reaching for one more crate is a second you don't have on the way back to the bell.

Cargo slows you down. That's the whole trade: the run that pays is the run that nearly doesn't make it.

Air is the clock

Your air is yours alone. Nothing another diver does spends it, and nothing you do reschedules anyone else. When it starts running low the game tells you plainly rather than hoping you notice a gauge.

In review

This one is in the submission pipeline at a games portal. It's playable here in the meantime, and the status on the board will change when theirs does.

Build log

  1. Renamed. The previous title shared its premise and its exact words with a 2025 feature film about a diver running out of oxygen — findable, confusable, and not worth arguing about later.

  2. Reshaped the opening. The first crate arrives sooner and the air warning states itself in words.

  3. Fixed a fifty-second hole in the middle of a dive that seventeen green test suites had never noticed, because all of them asserted how a dive ended and none asserted what happened during it.
