Get on one of the platforms. Wait on the platform, on which you are until it joins with the goal platform. Once the goal platform is nearly joined with your platform, roll gently off the platform into the goal. You should use your map to help guide you as you transition yourself onto the goal platform.
With pause buffering, you can reach the goal in less than five seconds. Hold up on the analog stick as soon as the level starts. Then, aim to pause between 29:15 and 29:51, ideally between 29:40-29:45. Once you learn the timing, it will become mush easier to reach the goal consistently with this method.
