Played for about 2 hours. Had to do a soft reboot twice. When the ball and another object hit the paddle(plane)simultaneously the game hangs. To my knowledge there is not way to exit the game except to reset the computer. This is unacceptable in my opinion. The software graphics people are better than this. This is the first game of this type I have purchased(although I have played the demo of several of them without them failing). I am not happy with Mega World Smash performance.
