Thank you for your fast answer!
It’s maybe a little too much to ask, but do you have any advice on how to do it? I’m not sure where to start to be honest…

So every screen uses the phon_shell screen. So shrink the game area around the phone_shell, and then go into your screens.rpy and modify all the screens to use that phone_shell. It wouldnt be *easy*, if youre not good with screens specifically it could take alot of trial and error to make sure everything fits.
You would need to redo everything from the quit screen, to the save screen, to the help screen, etc.
