game needs re-balancing, on the levels where u need to defend all you need do is change all stars to defense and sit back, you should tweak the power of ships and lower their production speed so that on these defensive levels you can actually have the attacking force take a star or two...
gameplay was easy to fair til I got the dragons, then it was boringly easy, maybe add harder bosses at the end or something to offset the power of dragons...
