CARDUME: Bioluminescent Shoal

CARDUME is a hypnotic dive into the abyss. You don't control a single fish — you control a living crowd of light. Hold the screen and the shoal swims toward your touch; tap quickly and it releases a pulse of light.

🐟 A LIVING SHOAL
Real flocking simulation: dozens of fish that move as one.

🌊 3 MAPS DOWN TO 3,000 M
Open Sea, Volcanic Trench and Sea of Ice — each with its own wildlife and hazards: hunters, anglerfish, jellyfish, hydrothermal vents, stalactites and orcas.

💡 PULSE OF LIGHT
Scare off predators, reveal traps and attract the plankton that makes your shoal grow.

🛒 SHOP, LEADERBOARD AND TUTORIAL
Collect pearls, upgrade your shoal and beat your high score.
