"Red Sky" is the game I developed on the Sigma game engine which I also developed. Watch the trailer here:
Red Sky was in development since November 2015 and was relased in January 2017. For most of its development, it was called "John's Crazy Mouse Adevntur" or "Sigma Engine". Later I named it "Red Sky" so that it didnt have a stupid name anymore. The Sigma Engine was developed from scratch and uses these libraries: win32. openGL, openAL, libOpusFile, libWebp. The game engine has light-maps, 3D-levels, and pathfinding. There is a secret level which can be found after beating the game with the right conditons.
