I really liked it; it was super polished. I liked the air traffic callouts, and the takeoff sounds helped me to remember when I had planes taking off I had forgotten about. I really got frantic when I realized that I had put a plane to land at the opposite end of a runway I had a plane taking off from, leading to a giant explosion and many casualties (in my mind). I really love how this shows how a videogame can tell compelling stories using its gameplay. Of course, the main problem I had with the game is that level 1 is super slow, because the tutorial is always there. It's hard to keep trying to get a better time when the tutorial keeps me slow. In general, a speedup button would be great if you keep developing the game. In any case, you got a great game on your hands, good job!
I'd also appreciate if you gave my game some honest feedback too!
