ArcticWolf is a C++ game engine built on top of SFML. It has been used primarily for some desktop 2D games for the Ludum Dare game jam.
Note that development of ArcticWolf has currently been suspended in favor of building TimberWolf as a more robust solution for 3D graphics and the Vulkan API. While this project will remain public and open source, it is not recommended to use this library for production use.
