So I went ahead and branched/merged this in to see it firsthand and at first could not tell the difference, went back and forth between the two versions a few times, but now I see it. It’s a really subtle difference, where rolling the head creates a slight perspective shift on the objects in the center of view, shifting the angle back and forth a few degrees, best way that I can describe it. Without the change, the image at the center of view stays at the same perspective when rolling the head side to side.
Have to admit that at first glance (ba-doom crash) I kind of prefer the first version unchanged, however can see how the perspective shift could be more comfortable or natural for most people. Herobound is one of the better VR games that I’ve experienced on the GearVR as it just feels different than the others somehow and is one of the only ones that I can spend enough time in to get the overheat warning - maybe this is in part why it feels that way to me.
In any event, thank you for integrating it into your branch and hosting it for everyone.
