Too big, waaayyyyyyy too big.
First : Thanks to Killian ( https://lunick28.artstation.com/ ) for the 3D tank. Unfortunately, I didn't have the time to use it in my project.
This project was big. Too big in fact. And will never be done. The project quickly became cluttered and unmaintainable. One day I will start again from the ground up and build something clean. Even though I learned loads of things along the way, I aimed way beyond my skill-set at the time. Let's call this project a proof of concept of a co-op tank game that I call "scuffed version of World Of Tanks"
The project used a remote SQL database, Photon plugin and Argon2I for password encryption. Even though it was far from being bullet proof.
