Some people have said that the exploit has been patched. I can confirm that it has not been fully patched, or that I have found a new exploit. After beating the game I started a new game and played to level 6 where I tried to get the three balls achievement. This is where I found it. Make sure you hit new game so you have no upgrades. On the way to level 6 I only upgraded my paddle size. When you get to level 6 throw the ball into the area and let it bounce around and BEFORE all the bricks are broken, quit out to the main menu and then continue. All your points will be saved and you can essentially farm points like before. Just make sure you don't lose any balls and don't lose all your lives. I was able to get 1 million points this way in about 15-20 minutes.
