A researcher trips over a banana peel, and a radioactive capsule falls into the drain. It lands in an aquarium, where a fish swallows it. Inside the fish, there’s a parasite — you. You’re tiny and extremely hungry.
The rule is simple: consume anything smaller than yourself to grow. When you grow large enough to eat the objective of the level, the creature will evolve right in front of your eyes. From a parasite to a mutant, to a crawler, a chimera, and beyond — there are nine stages, each one more unique than the last. With each evolution, your appearance changes.
Your journey takes you through the fish’s stomach, its body, the sewer, a settling tank, a pond, a harbour, the deep sea, bedrock, and finally, the Earth’s core. Each level brings its own challenges: blood flow, currents, acid, slime, diving herons, nets, darkness where light becomes bait, and stones to chew through.
Bosses stand in your way: a grease plug, a microbe colony, a giant pike, a warship, a nuclear submarine, a tunnel boring machine, and the living core of the planet.

How to play
**CONTROLS**
Guide the creature using the mouse cursor or your finger — it will swim in the direction of the pointer.
**DASH**
Press the right mouse button or the on-screen button in the lower right corner to get a burst of speed. This action consumes mass: it’s a cheap way to escape, but costly if you’re chasing something. Dashing also shakes off anything clinging to you.
**GOAL**
Engulf anything smaller than yourself. The progress bar shows how much more you need to grow to achieve the level’s target. Grow sufficiently, consume the goal, and the creature will evolve.
**DANGERS**
Anything larger than you can eat you. Beware of acid burns, slime that hurts and drags, currents that carry you away, and nets that catch you. A red sign above a predator signals an impending attack — time to dash!
**BOSSES**
A large goal can’t be swallowed whole; you must nibble through it layer by layer, dodging its attacks.
Pause the game using the button in the upper right corner. Completed levels remain unlocked.
