Derby Creek

A cozy fly fishing game with a synergy-driven roguelike economy

Every run, you walk down to a procedurally-generated creek with a fresh tackle box and a few days on the water. Each tackle item in your box carries various tags, and those tags combine to determine which fly you tie on next. 

Find your flow

Each fish has its own preferred flies, habitats, feeding depths, active times of day, and weather conditions that influence when and where they bite. Line things up for the species you’re targeting, and a single catch can turn into a massive score. Hit the day’s score threshold before you run out of flies, or the run comes to an end.

The Atmosphere

Patience is key in Derby Creek. You cast your line, watch the surface, and wait. In the morning, mist lifts from calm water. At midday, light reaches deeper pools. Evening brings gentle rises. At night, the creek changes into something else entirely.

Every run is its own adventure

Rigs, tackle items, flies, culinary boons, species, and the world itself all shape the catch. They deepen the challenge, reward skill, and give you new ways to outsmart the fish… or be outsmarted by them.
