To round up the basics: The source Code Repository is at: https://bitbucket.or...ius-game-engine and uses Git. (Discussion here);
The license is likely to be MIT as discussed here.
Currently, the engine is programmed using C++, OpenGL, and using SDL for Input and Windows Management.
The architecture is still being developed, and likely to be revised, but at the moment is largely functional with a strong emphasis on keeping the engine in neat segments.
If anyone has any issue or something else they want to raise, feel free to respond.
