Free · In‑App Purchases
Six more worlds, an endless mode and a Boss Rush, all in one purchase. No ads, no subscriptions. Worlds 1 and 2 and the Daily Catch are free to play.
A cat has built a flying machine. The sky is full of fish. Somebody has to do something.
Holy Mackerel is an arcade shooter in the old style: waves of enemies in formation, power-ups falling out of the sky, a boss at the end of every world, and a score that's never quite high enough. Drag anywhere to fly. Your machine fires on its own. Tap with a second finger when the cat's meter is full, and the cat deals with it personally.
EIGHT WORLDS, EIGHT BOSSES
From Light Fishfall to Fish in Space, every world brings new fish with new ideas: pufferfish that burst into spikes, jellyfish that drift and zap, electric eels with beams, octopuses that ink the sky, seahorses that shield their friends, anglerfish with a homing lure. Then something much bigger turns up.
THREE TIERS AND 72 STARS
Every world has three stars on every tier: clear it, rescue all five kittens, take no hits. Any two open the Hard tier, with tougher fish, new attacks and twice the score. Two on Hard open Holy!, which is exactly as unreasonable as it sounds. Every boss builds to a last stand, and Holy! saves the worst of it for last: you'll want your machine upgraded for that, and the map tells you how much power each world is built for.
SEVEN WEAPONS, TWELVE CATS
Blaster, Spread, Laser, Missiles, Harpoon, Rubber Duck and Zapper, each with five power levels. Every world starts you on the Blaster and you power up as you go; each world you clear adds a new weapon to the drops. The laser burns through a whole line and runs white hot; the harpoon skewers fish three at a time into a fish kebab; the ducks ricochet off one fish into the next; the Zapper's crackling arc locks on and forks through a whole row. And every world brings a new pilot, each with their own special: Mittens' squadron of rocket kittens, Biscuit's bouncing hairball, Goldie turning every fish to gold, Patches' broadside, Frosty's deep freeze, Luna's black hole, Midnight's cat nap, and more.
EVERY WORLD ITS OWN
A harbour, a coral lagoon, a festival in the sky, a pirate cove, the city at night, a lighthouse in a storm, the polar sea and outer space, each with its own music, its own trick and its own big moment: a net bursting with goldfish, schools that fall apart without their leader, a rainbow that turns fish to gold, a galleon's broadside, fireworks over the city, a gale, fish frozen in ice, and sardine tins drifting through a meteor field.
