Pygame Zero and PyInstaller working together

So I've managed to get Pyinstaller working with Pygame Zero packaging up a script, and it's actually not been too hard to get working, once I figured out a few quirks.

You can see the source code in this gist, which just loads and runs the Pygame Zero demo directly. I haven't tested this *thoroughly*, so (eg.) importing something in the main script may blow up - caveat emptor, etc.

If you're feeling brave and want to help test by running the demo itself, you should be able to download the .exe from Google Drive. Note that you'll need a gamepad with joystick that's recognised by Windows - please let me know if you manage to run it successfully.
