I love the game and app. But a suggestion, please add night time landings and takeoff and have running lights on the planes lit up just like the real airplane have. Makes the game a lot more realistic in terms of game play. Make it more enjoyable to the player. Add weather too!! Maybe a day or night time landing or takeoff in a storm. Make the airport more realistic too. Also, keep everything free!! That is a big plus for gamers like myself. I give this game four stars.
