I haven't seen any recent reviews for Overflight but yesterday I did stumble across the Twitter account of the chief developer for the game and noticed he'd tweeted that the game has been updated quite significantly.
A new plane (Bf109) has been added plus 2 new maps. Best of all though, they have apparently added full controller support which means that the Gear VR controller can be used like the sticks in a fighter plane to control pitch and roll (unsure of yaw).
I don't get my Gear VR for another couple of weeks yet, has anyone else played the updated version and can confirm the above?
I'm really excited to try this out now, even more than before!
