This game gets everything right. From great Stereoscopic VR rendering to amazing 3D sound, I havent found anything better on the iOS platform for use with VR goggles(Cardboard in my case). I recommend playing with auto-fire on as my arms get tired hitting the button on my Cardboard device. I also recommend sitting in a good chair that swivels, so you can spin around in place and then so shall the ship your flying does the same. Well done.
