WHY IT HITS

12 specimens, one breath. A single-trench survey run with a real oxygen clock — every detour costs air.
Sonar that matters. The scan pulse widens your grab radius and calls specimens toward the hull, at the price of sonar energy.
A living trench. Procedural caves from one seed: drifting jellyfish stings, half-buried boulders, amber hydrothermal vents, glowing air pockets.
Win on your terms. Surface through the extraction shaft with hull intact and air to spare for a fat score bonus — or die shining in the dark.
Runs anywhere. Pure browser 3D: keyboard, mouse-drag steering and full on-screen touch controls on phones.

HOW TO PLAY

Goal

Find and recover all 12 bioluminescent specimens hidden in the trench, then fly into the lit extraction shaft to surface. You win by surfacing with specimens in the racks. You lose when your oxygen hits zero or the hull crumbles — jellyfish stings and rock impacts bite, blue rings refill air.
