Wthe ball hits the side of the paddle, it ussualy just goes through the paddle and starts spazing, and then comes out when I move the paddle away. Bouncing on the top side works well, but I have some issues with bottom bouncing as well (when the ball moves below the paddle it starts moving straight until it moves out from under the paddle).
I'm a student. If my statements seem too absolute, feel free to coat them with "In my opinion..." or "I believe...".
