G - Gravitational Constant Bounciness - If you set it to 50%, if the ball touches edge or the black wall, it will go back with half velocity. If you set it to 100%, it will only go back with the same velocity and if you set it to 200%, it will go back with 2x higher velocity. Use mouse to move the objects. Hold mouse at the black wall and hold space to rotate it.
