Was not the point off it was to have a public repo so people can actually confirm you make a game in 1 month based on the theme?
I'm pretty sure the point is that Github is organizing this jam and they want to promote their product, git, and open-source software in general.
Also, requiring a public git repo doesn't actually prevent anybody from starting development before the jam actually starts.
Unless you can delete history of a git project it does.
If your day 1 commit is 10 gb project with 100 custom made assets I can deduct it is not your first day that you start working on that project.
You can delete the history of a Git repository.
So how the file history is going to work if we delete history of git? Will it show as new file or it just shows the last diff?
There are many ways to obfuscate the history of a git repo. The easiest is `git squash`, which takes multiple commits and squashes them into one large commit.
