^^Good Points^^
This defense game has just about everything one should have. You had a ton of upgrades to buy, which were all pretty useful. I like how you combined both air and ground combat, which made this harder. The difficulty level was also cool. You didn't mess around with easy stages. By stage 3 I had already taken some damage.
^^Needs Improving^^
I've found only one real flaw to this game. I found that if a ground troop breaches your defense and reaches the tower, they are impossible to shoot. You can aim at them, but your gun just physically cannot point and shoot to them, which ended the game for me.
