Needs improvement – 1945 - Airplane shooting game Review

First I just want to say that I do really enjoy and love this game. My only major issue is that I have been playing this game for well over a month almost everyday and it is so hard to get better planes without spending actual money. It seems like it will take forever at this rate to get more than the two “starter” planes. It’s to hard to get the diamonds to be able to buy more advanced planes. Hopefully with a future update you guys can do something about this.
