The 6 rating I gave you was for the orginal idea, the colorful effects, and the unique powers, and the fact that the game worked.
You didn't get the last 4 points because it wasn't really much of a game for me. It seemed like a happy random click fest, most of it was based on luck. You clicked in what seemed like a good location, but many times you would fall short of a goal because one nucleroid was just slightly effected by a black hole, and missed another. The stratagy was lost because after you clicked once, you couldn't do anything to help aim. It's just not fun to try to beat a level 40 times because each time something different screws you up.
