About the Game

About this game:

idle koi! is a server-driven idle pet collection game about hatching, breeding, training, and battling magical koi. Every koi begins from an egg and grows through its own genes, appearance parts, rarity, skills, lineage, and battle history. Breed different bloodlines for a chance at mutation and leap evolution, then form 3-koi teams and send them on expeditions that keep fighting even while you manage other teams.

Key features:

- Hatch starter, bred, event, and limited genesis eggs.

- Breed koi with inherited body parts, fins, decorations, expressions, colors, and hidden genes.

- Chase rare leap evolutions that improve growth, power, and long-term value.

- Build up to five 3-koi battle teams for idle expeditions and replayable battle history.

- Trade and manage valuable koi through server-authoritative ownership, with Steam Inventory support planned for the Steam economy.
