How can I create a new game based off of an existing one?

I’d like to create a copy of the Roll a ball game I made in a tutorial earlier to play around with and make changes to. I don’t want to risk messing up the original project, but I do want to save my test project because I may be using it as a base for a whole new game I’m thinking of building. I tried copying the folder for my Roll a ball project but cannot find a way to open the copy, only the original.

In short, I want to duplicate my game so that I can run some tests with the copy in Unity and save without overriding the original. Can anyone help with this?

Thanks in advance!

File > Open Project… > Open > (browse to folder) > Select Folder

If it is not a project folder, it will say “Selected folder is not a Unity project”

Make sure the folder you copied contains all the project’s files and folders, like Assets, Library, .csproj, .sln, etc

That worked, thanks!
