The dot moves based on the circle equation x^2 + y^2 = 10000 (10000 because the radius is the square root) with the X being influenced based on key choice and Y = root(10000 - X^2). the root function only uses the positive answer so I need to negate it based on the place and movement. The rate X changes because as you get close to the left side and right side the Y change increases drastically so I slow the X change down to give it a more fluid appearance
