It looks very cool! However, I couldn't find actual C++ source code of the engine... Could you point me to where the core C++ implementation is? I'd love to experiment, modify it and add my own features.
Our phrasing was a bit ambiguous, sorry for that. The game's source code is public (Zentera/assets/scripts), the engine's code is not.The scripting still let's you modify or create game features though! :)
