Gravity Pull is an immersive VR puzzle game for Google Cardboard and Daydream that was inspired by the popular Portal game. Solve 16 mind-bending physical puzzles by strategically placing cubes on switches to open doors. You'll need to carefully explore each room and view things from multiple angles. Can you get to the end? Gravity Pull uses an innovative input technique that lets you navigate each room using walking-in-place and puts YOU in control of where you are. No controller required and various studies have found walking-in-place to minimize cybersickness.

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. Joysticks should work automatically with the game if you would rather use them instead of walking-in-place. By default you will only move forwards and backwards with the joystick (to combat nausea) but there is an option in the settings menu (tilt to allow for full joystick movement.

Positional tracking enables highly immersive experiences on PC VR platforms (Vive/Oculus) such as walking input but this isn’t available on mobile VR platforms with as a result that many mobile VR apps are simple look-and-see or rollercoaster experiences. Gravity Pull was built using the VR-Step plugin (see Unity Asset store https://www.assetstore.unity3d.com/en/#!/content/60450) (patent pending). VR-step significantly increases existing interaction options of mobile VR platforms (Daydream Gear VR Cardboard) and lets you build highly immersive experiences that are usually only found on PC VR platforms.
