Killi and Milli

In the warm shallows, where the coral glows at dusk, live Killi and Milli, the two smallest and roundest pufferfish on the whole reef. Killi chases anything shiny. Milli makes sure he finds his way home.

Once a year the reef gathers for the Moonlight Feast, and this year the snacks are their job. Then, the night before, a rumble rolls up from the Trench. Jellyfish wake up cross. Eels stop pretending to be friendly. Every crab sets off in a straight line, and the snacks scatter into every corner of the reef.

So the two of them set out, reef by reef, to gather every last one before the moon is up. Bruiser the shark guards the way down. The Kraken Queen waits at the bottom. And a seal called Niko, who blows the best bubbles on the reef, has noticed two very small fish heading the wrong way.

How it plays

Each reef is a small maze. Swim around, pick up every snack, and do not get caught.

• Grow coral in front of you to build a wall. Creatures cannot get through it.
• Break the same coral to open the way again.
• Puff up when something gets close. For a moment nothing can touch you, and whatever bumps you is stunned.
• Snacks come in waves. Clear a wave and the next one appears somewhere new.

That is the whole game, and each of the 16 reefs adds one twist: currents that carry you, kelp to hide in, vents that erupt, snacks that run away, pearls that teleport, and nine kinds of creature with their own habits.

Two players, one keyboard

Bring a friend. If one fish is caught, the other keeps going and brings them back with the next wave of snacks. Plays just as well alone.
