This was a cool project! I don't remember seeing something like this before, it's very creative. I like the strategy element of determining where to build bunkers and predicting where ones might be good in the future. In the beginning, I was unclear of how the mechanics worked, so I put a bunch of bunkers in the middle of nowhere away from the bombings and wasted a lot of my resources. A little text popup in the beginning would solve that issue pretty easily. If you were to keep expanding on the project, which would be a good idea, it would be nice to have more actions for the player to do between bombings. There's a ton of stuff you could implement depending on the direction of the project. Great work!
