Hi!, not an issue, just a suggestion.

By adding the below to the button draw method you can get a really simple animation, this could be usefull if you update the tutorial in the future, as it took me a while to figure it our lol.

    if self.clicked == False:
        screen.blit(self.image, (self.rect.x, self.rect.y))
    else:
        screen.blit(self.image, (self.rect.x, self.rect.y + 5))
