Canvas-based game engine and toolchain optimized for rapid development. Features: Automatically creates a spritesheet for your assets and then loads the assets at runtime. Provides convenient API for drawing animated sprites in a canvas. Supports anchor points and rotation. Write code in JavaScript or other compile-to-javascript languages such as Coffee-Script. Uses browserify to compile your code which allows you to harness the power of code on npm. Everything from code to spritesheet is compiled automatically when you save. Bootstraps the resource loading process and optionally provides a basic loading progress bar.
