Well, it's not very good.... The hit detection is way off - so the zombie head bounces off my paddle about 1cm away from my paddle... No sound effects and no actual (terminable) goal to the game make it feel totally empty and makes you question why you are even playing it. Currently is 1 for 25 and the game shows no sign of ending... The key thing that is missing however is control. You do not feel like you ar in control of the ball. In the old breakout games there was the mechanism that the angle of the ball as it leaves your paddle is depedant on where on the paddle the ball strikes, giving you a greater degree of control - without this control you may as well be watching a movie, where the ball follows a pre-ordained script and you cannot outfox the AI.
