Playing the left hand side looks super weird that way, IMO. For me, the "face" of the paddle should rotate in a way that matches what you're moving onscreen. That Pong machine looks reversed to my eyes for the left player, similar to how it would look in Arkanoid if you rotated clockwise to move the Vaus left. Luckily, I don't know anyone with strong Pong memories, so I can set it up how I like it, rather than how they remember it.
