Added Resolution Screen and Fixed Open XR Bugs

VR Giants

VR Giants is a local coop VR game in which one VR player and one gamepad player work together. The VR player controls a giant and must protect and support the tiny player who is controlled by the screen player. The tiny player can use the body of the giant as an extension of the level.

We added an option menu allowing you to choose your screen resolution. We also fixed minor bugs with Open XR and the option to use the system default open XR solution. Mouse sticks again to screen now.
