TerrariaGL

A terraria clone made with OpengGL and C++

I've always loved learning about how games work at their lowest level, so this project was a perfect go for me. Everything here was created from scratch with only the help of a few libraries at my side. This was not only my first real OpenGL project, but also my first C++ project. The experience was quite challenging, but the knowledge that I gained from definetly made it all worth it!
