As Seth, your goal is to dig a tunnel downward to reach the cavern below. Along the way, gather as many fossils and gems as possible. A star rating meter at the top of the screen indicates your progress and current rating. Be careful to avoid collisions with obstacles from above or the sides. You can only move down, left, or right. Collecting fossils and gems increases your star rating; to achieve a three-star rating, you must collect all items in a level. The bar at the top shows your proximity to earning a higher star rating.
**Desktop Controls:** Use the left, down, and right arrow keys to dig—downward or sideways only; digging upward is not allowed.
**Mobile Controls:** Use your finger to direct Seth’s digging movements.
