You're a small fish in a boundless sea. Eat plankton and fish smaller than you, grow and climb the food chain — but watch out for anything bigger than you!

← → — turn. Ctrl (or ↑) — dash (uses stamina, helps you catch prey or escape a predator). Esc — pause.

On phone/tablet the game goes fullscreen: drag your thumb in the left half of the screen like a joystick to steer, touch and hold anywhere in the right half to dash.

Green outline — you can eat that fish. Red outline — it will eat you. Fish eat with their mouth only, so staying behind a predator's tail is safe until it turns around. Jellyfish aren't lethal but sting and shrink you — avoid them, until you're a Shark: then you eat them.

A pulsing red glow at the edge of the screen warns of a predator just out of view — the bigger and closer it is, the brighter and faster it beats; a double arrow means it's coming for you.

Become the sea's biggest predator — the Sea King — and then grow to the maximum size!
