Halfglow in play: a small lantern spirit beside moon blocks over a row of spikes at night

What it solves

The gap

Platformer levels break silently: a changed jump height can make a gem unreachable, and replaying every level by hand after each tweak is slow.

What it is

A finished, tested platformer whose every level a search bot proves, with its levels and movement rules in one config file.

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 short platformer on itch.io, web portals or your site.
  • Learning deterministic platformer physics, replays and search bots in TypeScript.
  • Building a branded platformer mini-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, movement rules (coyote time, buffering, jump heights), levels drawn as text, daily pieces, colours and sound.

Levels with a proof

npm run solve finds a run through every level with every gem and records it; npm test replays the runs through the real simulation and finishes 30 daily levels.

A finished game

20 levels and a daily level, the day/night swap, gems, par times, three stars, lantern checkpoints, instant respawn, a replay on the title screen.

Tests and a guide

129 unit tests and Playwright browser runs, a size budget, an upload zip for itch.io or any static host, and a guide to new levels, tiles and moves.
