Epoch is a game engine I'm working on during my free time. As I am primarily working on the engine at school, especially the graphical side, I have chosen to mainly work on the editor for my engine as for now.
I've got big plans for this game engine and plan to use it later to create small games. Epoch also allows me to challenge myself in a way I am not able to while working on Aurora in school, as nobody depends on me finishing a feature fast and letting it "just work".
As I can sit and work on a feature until I'm happy with it, I can learn much more and take those features and copy them into Aurora.
