Click on the ball and hold down, drag and release. Press space to change the platform! Press the up and down arrows to change erraticity! Press the left arrow to show and right arrow to hide the erraticity slider! Press w and s to change back drop Press a and d to change the color of the backdrop Press q and e to change the color of the ball Press 1 and 2 to change the color of the platform Press r to reset it all The more erratic it is, the weirder and counterintuitive the ball acts. 30 is a lot of erraticity so I recommend just setting it at 3 to see the effects first. Press and hold 2, e, and d at the same time for a cool effect
