Oh this is neat!! Very easy to understand but surprisingly addictive. I liked the calming music and the background color change was a nice change of pace. I found the easter egg :)
It would have been cool to see more powerups, like ones that make the paddle wider, or slow down the balls. Also, it was a little hard to keep the extra balls in play, but they occasionally would help me score an extra point or two so I still tried to pick them up.
Very neat entry with a unique take on pong.
