I got killed by the Zombie Giants. I kept respawning right next to them, only to immediately get killed in a single stroke before I could move. Seriously?
I positively love the idea of this game, but two problems kept popping up: 1, the lag, which, in a game like this that requires instant feedback, can be killer. And 2, the speed and frequency of the planes...maybe I'm just a terrible, but I would often avoid one plane by moving to the side, only to have another plane enter from that side and completely obliterate my flock. Could I have some sort of "plane approaching" warning, or maybe a bigger field of vision without a bigger field of play?
The character needs to be able to either jump or walk backwards while shooting. There is no good way to deal with being surrounded by zombies, otherwise.
