Thanks for your review. I moved this game to FPS, and hope it will be more enjoyable. Now, there are zombie waves :)
I need to work on rescuing civilians to have more game mode in this game.
fun to play. After 15mins trying to avoid the disasters, my high score is less than 30... Some ideas for improvements: sounds (when an airplane is selected, the destination is set), and different colors or shapes for every single state. It is hard to decide if a plane is flying, landing, or is already landed.
