What it solves

The gap

A platformer lives or dies by its jump feel, and every new level needs proof that it can be finished.

What it is

This template ships tuned physics, levels you edit as text and a bot that plays them with the real physics to show they are beatable.

How you use it

Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.

Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.

Who it is for

Use it when

  • Publishing your own pixel platformer on itch.io, web portals or your site, or as a base for level packs.
  • Learning how a complete pixel-art platformer is built in plain JavaScript and Canvas 2D.
  • Building a branded mini-game for a client.

Built for

  • Web and indie game developers who know some JavaScript.
  • Developers who want a finished, tested game to build on instead of a blank canvas.

What you get

Levels as text

Each level is a list of strings: # ground, - thin platform, ^ spikes, o coin, * gem, S spring, C checkpoint, M W V moving platforms, e h b enemies, F fake wall and G goal.

A bot that plans

Every few frames the bot tries dozens of short input sequences with the real step function and keeps the one that brings it closest to the goal on a route map, never dying and always landing.

No build step

Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.

A smoke test

A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
