RN24: In general, rhythm games don’t have graphics so much as displays. Most of the time the player’s eyes are focused on the series of notes flowing down from the top of the screen, and everything else that’s happening visually is actually sort of a distraction.
But what if you simplified things? If you made the rhythm constant, and didn’t specify which button the player has to press in time with the music, you could free his gaze and let him look wherever he wants. In that case, you might as well reward him for skilled play with some panty flashes, and punish his mistakes with a muscular male crotch.
