Punter.js

Punter.js is a minimal 2D game engine built to help new developers learn JavaScript by making browser games. It ships as a single file with no dependencies and no build step, so you can drop it into an HTML page and start coding immediately. The project comes from Orca Scan, a company that builds barcode scanning software, and grew out of their internal efforts to make programming education more accessible.

The pitch is simplicity over power. Modern game engines are complex, with asset pipelines, physics systems, and tooling that can overwhelm a beginner before they write a single line of game logic. Punter strips that away. You get a canvas, a game loop, and enough structure to build classic games without wrestling with configuration.

The repository includes working examples of Asteroids, Pong, Breakout, Tetris, Snake, and a platformer. Each demonstrates a core mechanic, vector movement, collision detection, gravity, grid systems, so you can study how the pieces fit together and modify them to learn. The examples are playable on the website, and the code is open to inspect.

It runs in the browser with no server required. You write your game in plain JavaScript, open the HTML file, and it runs. That makes it suitable for classrooms, workshops, or self-taught learners who do not want to install tooling before they can experiment.

The engine is open source and hosted on GitHub. Licensing details are in the repository. There is no pricing because there is nothing to pay for. The audience is students, hobbyists, and educators who want a zero-friction way to teach or learn game development fundamentals in JavaScript.

Where it fits in the landscape is as a teaching tool rather than a production engine. You would not ship a commercial game on Punter, but you might use it to teach someone how game loops work, how to handle input, or how to detect when two rectangles overlap. Once they understand those concepts, they can graduate to heavier engines with that foundation in place.

Documentation lives on GitHub alongside the source. The maintainers are the Orca Scan team, so support would route through the repository or their company site rather than a dedicated Punter support channel.
