Game engine
Developed for Quake-style 3D games, but it is possible to create games of other genres.
The beginning was laid a long time ago, the development of the latest version of the engine started from scratch in the fall of 2018. Before that, there were other versions that were not very successful.
One of the engine versions was called Unity and was developed in 2002. It was a clone of Quake 3 Arena (only level renderer). At that time, I was inspired by Carmack's code, the sources of Quake1 and Doom2 were already available.
