SEPIA

SEPIA is a stealth hunting game played as a cuttlefish on a reef. Camouflage is positional: stop swimming and your skin settles into whatever lies beneath you, sand, gravel, weed or rubble. The match is drawn live from the seabed itself, so hiding is about where you park, not a button you press.

Move with WASD, arrows, the mouse or a touch drag. A jet burst gets you clear fast and wrecks your camouflage. Crabs graze near their burrows; to catch one you flash the passing cloud, rolling dark stripes that freeze a crab long enough to close in and strike. The display is the brightest thing on the reef, so the same stripes that hold your prey show every hunter where you are. A startled crab bolts for its burrow, so the strong play is to cut it off before you flash.

Reef sharks hunt by sight and escalate through suspicion, alert and chase. Morays ignore camouflage entirely and guard their rock holes with a telegraphed lunge. The barracuda reads movement alone: freeze mid-chase and it swims past you. Every crab eaten raises the danger tier, feeds you, and refills half an ink sac. A full sac fires on its own to buy you out of one bite. Hunger never stops falling. The leaderboard counts crabs eaten in a single life.
