I've decided to learn Unity Collaborate as a way for our game programming team to collab on the game project.

The only downside of using Unity Collaborate is because they only offer 1GB of cloud storage and can support only up to 3 collaborators for the free version of Unity.

It works pretty much like Github and I think it's going to take only a little time to adjust to the interface system.

We faced some problems in figuring out some errors that I'm not really familiar with so it took a few testing.

I've also found a tutorial on creating and coding the Board Game Movement on youtube.
