  • QOI

A generative koi breeding game, where koi pass down features, such as their pattern, to their offspring.


The fish’s patterns are procedurally generated, based on the parameters that are encoded in its genome. These parameters make each fish’s pattern unique as well as deterministic. When the fish reproduce, the parent’s parameters are combined. The inheritance of feautres can be traced back through generations.


The pond goes through a day-night cycle. By daylight, the algae can grow. The algae population is dependent on the pond’s oxygen and nitrogen level and it grows procedurally according to these environmental circumstances. In turn, it influences oxygen and carbondioxide levels.


The game is about ecosystems, the chance of evolution and the zen beauty of a pond.
