Nicely done.
Very interesting game here, the simple design of the game worked very well. The music that started playing as your about to die was a very good touch but it caused one problem for me. I always prepare for the planes when I hear them but the music drowned them right out which caused a few game overs for me. I also love the story telling during the battle as well. I also noticed that when the engineers hit max whatever your stats at they go to that stat.
In ending this was a very good game and I'm looking forward to those medals!
