Easy Source Control for 2 people

Hello!

Me and my friend are make a game, and we need to connect to the game files easily, without transfering them by any program or something like that. We are not doing it in the same house/place, so it can’t be local. I tried looking through some programs, but all of them didn’t work for me.

What I tried using:

Perforce
Git
VisualSVN
TortoiseSVN

If you know any program, please recommend it! It has to be not hard to understand.

Sorry for any mistakes, English is not my first language and this is my first post.

Personally, I like Azure DevOps Services | Microsoft Azure
It has a repo, boards for sprints and kanbans, as well as other stuff like pipelines and test plans.

It’s really good.
