The immediate problem with this game, the problem that made me stop playing before I'd wasted two minutes on this game, is the range of the opponents. I believe I played in "Long Town", one of the "Easy" zones. The planes began firing the instant they showed up on screen. Thus, it's impossible to stop them from hitting your base. Five planes in, I'm down. This should not happen. Take a look at games like Defend Your Inglor for inspiration here. There should be a line that ranged opponents have to reach before they can fire, and it should be reasonable that the player could defeat them before they reach this mark. At least, in the Easy levels. That's where this game missed, and that's why I'm giving it such a low score. Sorry.
