Lullfin at dawn: an angler on a low-poly lakeshore reeling in, the tension needle in the green band

What it solves

The gap

Fishing games need dozens of species with fair fights and a pace that keeps players going; tuning spawn tables and reel physics by playing is slow, and so is drawing every fish.

What it is

A finished, tested fishing game with an ending whose fish, spots and pacing live in one config file and are proven fair by a bot.

How you use it

Unzip, run npm ci and npm run dev, then edit src/game.config.ts; npm test checks the game again in seconds.

Source code of a real, playable game to reskin and learn from, with its proofs built into the tests.

Who it is for

Use it when

  • Publishing your own cozy fishing game (a river, a reef, an ice hole) on itch.io, web portals or your site.
  • Learning seeded spawn tables, fixed-step physics and automated pacing tests in TypeScript.
  • Building a calm branded browser game for a client.

Built for

  • Web and indie game developers who know some TypeScript.
  • Studios and freelancers who make branded browser games.

What you get

One config file

Species with spots, hours, weather, baits, depth, rarity, size and fight; spots, rods, baits, goals, the weather deck, cast and reel tuning, colours and sound.

Fish with a proof

A bot with a human reaction delay lands every species at three sizes, doing nothing loses every fish, rarity is checked over 200,000 rolls and 20 whole games prove the pace.

A finished game

25 fish, four spots, day and night, four kinds of weather, a journal with records, unlocks, a fish of the day and a master-angler ending.

Tests and a guide

35 unit tests and Playwright browser runs, a size budget, an upload zip for itch.io or any static host, and a guide to adding species and spots.
