Gideros is a free, open source game framework available at http://giderosmobile.com.

Gideros comes with all the tools you need to deploy a game, such as a lightweight IDE, players for desktop and mobile devices, a texture packer, and a font creator; there are also third-party tools. Gideros uses an object-oriented approach to game creation—it provides a simple Lua class system. The core framework can be extended using plugins, which are written in native code such as C++, Java, or Objective C. You can try Gideros live and online at http://giderosmobile.com/code/.
