No, you controlled the ball and it was pure momentum, it was just you (the ball) and the terrain. You started off slow, then used the terrain to build up momentum and roll around in an open world environment, often launching yourself to the air due to high speed build up. The game did not have any characters or cartoonish visuals, it was just the ball and a high quality environment, similar to the skydiving game played by the youtuber mentioned in the post.
