[PyGame] Screen is all black and nothing is updating, but I can't figure out why.

What is your goal here?

In your button call

    def run(self, controller):
        for obj, info in self.objects.items():
            obj.run(controller.screen, *info['finish_funcs'])

You are only sending the screen and info back, the buttons run does no callback to anything.

                'finish_funcs': [],

Like this will print out as your button is held down

                'finish_funcs': [lambda:print('test')],
