Look at the score counter in any mini: the digits never shift sideways as they count. That is because every game screen uses a monospace typeface, where all characters occupy the same width. Proportional fonts would make the score wiggle and steal a fraction of your attention every frame. In fast games, tiny visual noise costs reaction time. Monospace type is one of those invisible craft decisions — boring to explain, impossible to unsee once you know.
