Perfect Ball

You go on a long journey as a ball. All you have to do is get to the top.

You can't move alone. Because you're a ball without arms or legs. However, even if you can't move on your own, it's possible to move the ground you're standing on. Rotate and tilt the ground so that you can climb up!

Of course, it will not be an easy journey. You can't stop or jump up wherever you want. Also, all kinds of obstacles will interfere with you.
