There is one question
Does creators themselves played through their game?
Tons of small bugs (like indestructable air bases), the beginning is just boring as hell, tons of lags (even they are pretty easy to get rid of if authors is even small amount thought of optimizing their project).
Annoying music (Yeah, I could turn it off, but still the music selection could be more thinked of).
Balance is quite bad. This makes gameplay boring, just spam your best unit ("suggest 1st tanks, 2nd planes, and latest naval. got me good enough results") and wait while them crawling (slow as a turtle) up to enemy lines. You shoulkd add some speed-up button at least.
Liked graphics, still somewhat crappy even for pixelart..
Overall - man, you should delay the release for 2-3 mounth more to patch balance, pick music, test all of the stuff, tweak the gameplay (throught the balance). This state of the game is "unfinished"!
Maybe you should make Massive War 1.5 to fix all this small by themselves, but in summary huge, looses.
