Written in Haxe, games are compiled to HTML5 and Flash, with support for mobile browsers. The HTML5 renderer uses WebGL, with fallback to canvas. Rendering in Flash uses Stage3D. Native Android and iOS apps are packaged using Adobe AIR. On top of being high performance and cross-platform, Flambe recognizes that assets and workflow are critical to game development. It includes battle-tested support for importing Flash animations, bitmap fonts, and particle systems. Live asset swapping lets you modify an asset and see the change in your game automatically, with no recompile or refresh. When you need to make a code change, Flambe recompiles and automatically refreshes your browser tab, all in under 2 seconds.
