Needs a unique touch...
The kinematics in this were kinda sketchy - you may want to think what path the ball ought to take when hitting different areas of the block/paddle from different angles. Other than that (and the problem of the ball's y-velocity missing the paddle altogether), it's a pretty accurate rendition of the original.
In the future, though, when you remake an old game or expand on it, you may want to consider adding your own original elements. Otherwise, it's not really anything new. For instance, you could have the ball accelerate towards the paddle when the mouse button is down or something. Well, good luck in your future endeavors!
