An excellent game
I really enjoyed the strategic aspects - allocating recruits, choosing where to defend (especially at the beginning where you don't have much intelligence). It was harrowing at times and receiving a lucky bonus (+10 pilots, double factory output) at the right time saved me; although towards the end I feel like I was only receiving negative bonuses (no new recruits, no factory output, etc.).
The first suggestion I would make is tying some of the positive/negative bonuses to what happens rather than just be random. During mid-game I successfully defended 4 areas from major attacks (losing a lot in the process) only to be hit with the negative morale - no new recruits. Such a defense should have produced some positive morale.
The other suggestion is the ability to build more and know more about my odds. I didn't really understand how big of a difference there was between the two planes and it seemed the more powerful plane go wiped out just as easily. As for building more - what about flak cannons (or other air defense) that would be restricted in the same sense of the pilots/spies (you cannot move it from where you build it).
The hints and tips button provides neither which is a disappointment.
