Pretty fun, but you should add some sort of way for the player to control the angle the ball travels based on where they hit the ball with the paddle like in many of the popular 'brick breaker' style games.
Not bad at all for a first try with Unity. I'd suggest adding some sort of padding around the middle to prevent the player from "jumping" all over the map.
And powerups!
