Remove Y-axis clamp from Tap to Move, Drag to Look Script

Hello,

I got a Tap to Move, Drag to Look script from the unify wiki:

And it works a treat, except the y axis is restricted and i can't see why. I've had a good look at the code, and considering it's C# and i'm used to Java, i'm pretty sure i'm misunderstanding something in the rotate function.

     void Rotate()
 {
     Vector3 lastDirectionInGlobal = _camera.ScreenPointToRay(rightFingerLastPoint).direction;
     Vector3 currentDirectionInGlobal = _camera.ScreenPointToRay(rightFingerCurrentPoint).direction;
     
     Quaternion rotation = new Quaternion();
     rotation.SetFromToRotation(lastDirectionInGlobal, currentDirectionInGlobal);
     
     ownTransform.rotation = ownTransform.rotation * Quaternion.Euler(0, kInverse ? rotation.eulerAngles.y : -rotation.eulerAngles.y, 0);
     
     // and now the rotation in the camera's local space
     rotation.SetFromToRotation( cameraTransform.InverseTransformDirection(lastDirectionInGlobal),
                                                 cameraTransform.InverseTransformDirection(currentDirectionInGlobal));
     cameraTransform.localRotation = Quaternion.Euler(kInverse ? rotation.eulerAngles.x : -rotation.eulerAngles.x, 0, 0) * cameraTransform.localRotation;
     
     rightFingerLastPoint = rightFingerCurrentPoint;
 }

Any tips would be greatly appreciated.

Thanks.

Simon.
