The game was definitely difficult like others have said, but I love the idea! I haven't seen any other games that play like this before, so congrats on the idea. The gameplay was definitely hard, but you could probably improve the speed of play and player engagement with some options like being able to deploy multiple planes, or letting the player decide when to deploy countermeasures. Overall, I think this is a great base that could definitely be built upon!

I thought the gameplay was quite coherent with the theme and the historical accuracy. 
It was quite hard to find the targets though, but I guess that was the point historically at the time :-D
The artstyle was really nice as well, I liked the way that more of the map would become visible as you flew in circles above the environment.
