Pong Blitz

So I wanted to play with some Unity physics in 2d so I made a pong game.
W - Move The Paddle Up
S - Move The Paddle Down
L.Shift - To Stop the Paddle

The game ends when there are no more balls left on the field. 
You are trying to score more than the opponent in that time.
Beware Multi-Ball is the only powerup I made so far.
