Design

The design is based on simplicity and to not require any manual in order to understand how to play, even if no prior knowledge of how Pong is played.

Black is used as the background colour with dark grey as additional feedback, also part of the background. Light grey indicate solid surfaces which can't intersect with each other. The light grey ball will bounce on all light grey surfaces. Red indicates the area where the turn will end if the ball touches any one of those.
