Grow Into the Sun 2

A scientist slips on a banana peel, and a radioactive capsule rolls down the drain. It ends up in an aquarium, where a fish swallows it. Inside that fish lives a parasite — you. Tiny, and very hungry.

One rule: eat anything smaller than you and grow. Grow big enough to eat the level's goal and the creature evolves right before your eyes. Parasite, mutant, crawler, chimera… nine stages, each one less like anything on Earth. Every evolution drops a new look.

The only way is down: the fish's stomach, its body, the sewer, a settling tank, a pond, a harbour, the deep sea, bedrock and the Earth's core. Each level has its own rules: blood flow and currents, acid and slime, diving herons, nets, darkness where light is bait, stone to gnaw through.

Bosses guard the 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.

Finish fast to earn stars. How it all ends, fans of the first game already know.
