Like that?
Almost :)
You don't need to put them in zip archives. You should add folder itself. for example:
https://github.com/bryengx/GameOff2022
That way if you have someone else on the team they will be able to do changes to specific files or add more files. And all you would have to do to receive their changes is use pull comand.
I guess archives might still work out for one man team. :)
