chem is a command line tool and JavaScript code library that helps you to rapidly prototype 2D canvas-based video games for the Web. It automatically creates a sprite sheet for your assets and loads the assets at runtime, provides an API for drawing animated sprites in a canvas, and uses browserify to compile your code, allowing you to harness the power of code on npm. Everything from code to sprite sheets are compiled automatically when you save. It handles the main loop and frame skipping, provides an API for keyboard and mouse input, and bootstraps the resource loading process, optionally providing a basic loading progress bar.
