In Pure Sky Rolling Ball, players control a small spherical entity that rolls through a celestial body. The entity responds to gravity, moving and rotating in response to different environmental surfaces.
The main objective is to reach the end of each level without being ejected from the surface. The challenge arises from navigating the entity's movement and rotation to overcome obstacles and stay within the playable area. Players can try different approaches to complete each level. The game is available online, requiring no download or registration to access and play.
