Mobile games usually aren’t controllable with a keyboard and mouse. Being able to run them doesn’t do much good if you can’t control them.

Most Android emulators allow you to bind keys to click or drag on certain regions of the screen.

I tried a few mobile exclusive FPS games through an emulators many years ago and I managed to get the controls feeling pretty close to playing a native PC game.

If it’s a pure Linux phone then apps would be installed through the command line and could be easily auto updated via a script.

So if you don’t install a terminal emulator on the phone itself and only access the command line through something like SSH. You wouldn’t have to worry about an app store at all ideally?
