BADASS.
I'm really digging this game. On the other hand, I can tell it still needs a ton of work. Here are a few suggestions for improvement:
-occasionally I could not see the status of my plane. It was usually just one plane
-include firing arcs of planes to take some of the guesswork of whether a plane was entering or crossing a line of fire
-allow plane configuration once a technology is found before missions. I never used the poison cloud except when I needed to use something of the sort on a boss plane, where I didn't have it
Suggestions to people having trouble with slow enemies: remember that your planes do NOT need to fly maximum distance! There is a minimum speed they can fly however so keep that in mind.
