What is it?

Excalibur is a 2D game engine written in TypeScript that targets the HTML5 canvas. It handles the common engine plumbing for browser games, so developers can focus on gameplay, whether they are new to game development or experienced with it.

The project is aimed at building 2D HTML/JS games and is cross-platform, with automated testing on supported desktop and mobile browsers. It can be installed from npm as the `excalibur` package, and a NuGet package is also built from the repository. The engine is at version 0.x, so APIs may still change between releases.

Excalibur is distributed under the BSD 2-Clause license, which permits use in commercial projects. Documentation, samples and an API reference are maintained on the project's website.
