You like Beamer but need to use PowerPoint? Fake Beamer is for you!
I don't fully appreciate (read: understand) Microsoft PowerPoint. This template has undergone only mild testing via my Mac (Monterey) and a Windows 11 VM. I suspect there to be some bugs, particularly associated with the required fonts.
You can properly install this as what Microsoft calls a "Theme" using the fake-beamer.thmx file.
The fake-beamer.potx file is the "Template" file.
I do not grok the difference between these, but both should work.
You should also be able to just use the example presentation, example.pptx.
What would Fake Beamer be without Computer Modern fonts?!
They are so important, I even included them in the repository, computer-modern-fonts/.
You should install them.
Learn to do this here (Mac) or here (Windows).
The classic Beamer footer can only be seen by enabling "Headers & Footers"!
Do this via Insert, Header & Footer and then fill out as appropriate.
I don't really like it either, but it's the Beamer hallmark.
In either case, you can change that bright blue to something else by selecting all your slides, then (on Mac) Format, Theme Colors.
Then you can change Accent 1 to your favorite color.
You can also change the font colors.
The other named colors are not used by the theme.
Git isn't built for such PowerPoint files, but I appreciate comments via Issues. I also will accept fixes via Pull Requests if you can explain them well.
