What it solves

The gap

Puzzle games live or die by their levels, and hand-made levels need endless testing to be sure each one can be solved. Building the game loop, saving, sound and layouts on top takes weeks before the first level is fun.

What it is

A finished, tested puzzle game whose levels are generated and proven by a solver, with its look, rules and difficulty curve in one config file.

How you use it

Unzip, run npm ci and npm run dev, then edit src/game.config.ts; npm test re-proves every level.

Source code of a real, playable game to reskin and learn from, with the level proof built in. Not an engine or a drag-and-drop builder.

Who it is for

Use it when

  • Publishing your own reskinned one-control puzzle on itch.io, web portals or your site.
  • Learning how to generate and prove puzzle levels in TypeScript.
  • Building a 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

Title, logo, save key, every colour of the harbour, hearts and tolerance, level names and the difficulty curve: boats, walkers, causeways, reefs and the moon's speed per level.

Levels with a proof

Each level is drawn around an intended tide and then checked by an exact solver. The autopilot clears every level without losing anyone, and from level 3 no single fixed tide can.

A finished game

24 levels and a daily level, three hearts and stars, a gauge that shows the safe tide, warnings over travellers about to be caught, saves, and layouts for desktop and phones.

Tests and a guide

37 unit tests and Playwright browser runs, a size budget, an upload zip for itch.io or any static host, and a guide to reskinning, tuning the campaign and adding new rules.
