Gravity Pull is an immersive VR puzzle experience for Google Cardboard that uses an innovative input technique called VR-Step. You don't need external controllers to move in Gravity Pull, just walk in place!Solve 16 mind-bending physical puzzles by maneuvering objects through space. You'll need to carefully explore each room and view things from multiple angles. Can you get to the end?VR-Step changes the way players can explore virtual environments with Google Cardboard. Where most Cardboard apps are simple look-and-see experiences, VR-step lets you navigate using walking-in-place and puts YOU in control where you are. VR-step removes the need for a controller and can also minimize motion sickness. We highly recommend having a Cardboard V2, which is any headset that has the capacitive touch button. The Cardboard V1's magnet switch IS supported, but may not work consistently.
