You don't control it.
You keep it alive.
Kritterz is a tiny creature with its own hunger, fear and curiosity. Drop food, let it find tools, choose its instincts, and watch it evolve from a Sproutling into a World Ruler with a colony at its back.

Ten stages. Five bodies. One stubborn little critter.
It thinks for itself
Seven drives compete for control every moment. The most urgent one wins. You only get to tip the scales.
Example drive readout
You shape its instincts
At milestones 10, 20, 30 and 40 the world pauses and you pick one of two traits. The choice is permanent.
The world pushes back
Predators evolve right alongside your critter. From milestone 35, a siege of four Leviathans arrives every 45 seconds.
At milestone 10, it stops being alone.
A well-fed critter reproduces every 45 seconds. Followers choose their own traits, rally to the leader with Swarm Summon, and the run only ends when the last of them falls.

Dreamed up by an 11-year-old.
Kritterz started in the imagination of Michael Malone, age 11.
Michael had a big idea: a tiny creature that thinks for itself, hunts for food, dodges predators and grows into something unstoppable. He poured every detail into an AI, from what his critter eats to what hunts it and how it evolves, and watched his words turn into a real, working game.
With a little help from his dad, Kritterz hatched. Now it's out in the wild and ready for everyone to play.

Keep it alive.
One critter. Fifty milestones. Every run plays out differently because the critter makes its own choices.
