SDL Framework (SDLFW)
SDLFW is a cross-platform framework from the powerful SDL library to create your own 2D games with the Lua programming language.
It's easy-to-use, free, open-source, and works on Windows and Linux.
This engine is not an attemp to re-inventing the wheel. It is a more learning-oriented project than something intended to provide a wide set of features. The approach to the OpenGL in this engine is something very experimental born from my own thoughts and can be usefull in future. If you want to help for your portfolio just ask: the TODO list is very long :)
