is a given name to a graphics engine which provides basic and essential resources to develop games or graphics applications 2D or 3D. For now, is possible to develop games for Windows , Linux , and Android . The intention is to provide the minimum necessary for game development or graphics application using minimal dependencies. The engine is written in C++11 language using OpenGL-ES on its core and LUA as a scripting language. Note: Although there is an effort to migrate the whole project to C++11 still there is a lot of mixedC code and maybe is not the best
