Sowmere in play: a gardener in a straw hat on a hedged island with a seed pod, a soil bed and one sapling already planted

What it solves

The gap

Push-puzzle levels are easy to make unsolvable by accident, and finding the fewest moves for a fair par by hand is slow.

What it is

A finished, tested push puzzle whose levels are text and whose solvability and par an exact solver proves.

How you use it

Unzip, run npm ci and npm run dev, then edit src/game.config.ts; npm test proves every level 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 push puzzle or grid puzzle on itch.io, web portals or your site.
  • Learning puzzle solvers, deadlock detection and proven level design in TypeScript.
  • Building a branded puzzle mini-game for a client.

Built for

  • Web and indie game developers who know some TypeScript.
  • Puzzle designers who want every level checked by a solver.

What you get

One config file

Title, logo, save key, the twist, stars, hints, the daily generator, the levels as text, colours and sound.

Levels with a proof

On every npm test an exact solver solves every level and daily garden and finds the fewest moves, the par.

A finished game

30 gardens, a daily garden, three stars, unlimited undo, hints and a warning when a pod is stuck.

Tests and a guide

26 unit tests and Playwright browser runs, a size budget, an upload zip for itch.io or any static host, and a guide to drawing levels and changing the twist.
