🪄 Sorcery 🪄

Sorcery is my hobby game engine that I started developing during the second year of my BSc to learn about the technologies behind video games. I have used it as my BSc and MSc theses. Generally it lacks quite a few features, mainly because I can work on it only in my free time and I also keep reworking systems forever and ever as I learn new things. Basically I use it to implement, integrate, and play with ideas I come across as well my own.
