Songbridge in play: round creatures cross a river on coloured stepping stones raised by the note pads

What it solves

The gap

Hand-made puzzle levels take long to design and are easy to get wrong: one unsolvable level and players leave.

What it is

A finished puzzle game whose levels are generated from short song recipes and proven solvable by a solver bot on every test run.

How you use it

Unzip, run npm install and npm run dev, add a song to src/game.config.ts and run npm test to check it can be played for three stars.

Source code of a real, playable game to reskin and learn from, not an engine or a drag-and-drop builder.

Who it is for

Use it when

  • Publishing your own music puzzle game on CrazyGames, Poki, itch.io or your site.
  • Learning procedural level generation with a solver that proves levels are fair.
  • Building a branded music game for a client.

Built for

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

What you get

Write songs, not levels

Each song is a short recipe: tempo, key, length, gap sizes and the chance of thorns, low rocks and golden notes. The generator writes the melody first and builds the level around it.

Proven fair on every test run

npm test lets a solver bot with human-like reaction play every song for three stars and checks 60 days of daily songs. Test players also prove that mashing buttons loses.

Reskin from the same file

Title, logo, tagline, world names and colour themes, note colours and musical scale, the note sound of each world and the creature colours.

Accessible by design

Every note has its own shape, number, height and colour-blind-safe colour; a visual beat, a note guide and reduced motion make it playable with the sound off.

Ready for web portals

One command builds CrazyGames (one-file build for their uploader), Poki and itch.io or own-site versions and checks download size.
