When it does, the graphics will change and the player will mode-up to a higher mode and earn more points for each beat.
The top part shows the name of the mode the player will be in, which will change (or mode-up) if the bar below the name fills completely.
The middle part is the main area of play, where the player's paddle is on the right edge of the screen and beats move from left to right before being reflected back.
The bottom part of the screen shows the name of the mode the player will move down to (or mode-down) if the bar next to it fills completely.
In the bottom right corner is the bonus multiplier that shows how much additional points each beat will add to the player's score.
This feature also means that high scores will not be saved unless the player successfully completes the level.
