great game ! great atmosphere, great gameplay, great storytelling, and good music too !
the gameplay is original, mixing driving and escaping the zombies.
Some points may be weird, but find a logic according to the end,(and the logic of a zombie outbreak, like one escapee can infest a whole new city over time) and to the gameplay needs (otherwise you dont see helicopter coming and they just destroy you from behind, without seeing them, or a chance to dodge or to destroy them)
And you know, making a game is a hard and long work, i'm actually glad the developper made it for our fun, than complaining on few lacks or details that seems weird.
It may takes dozens or hundreds of hours to learn how to code, write ideas, code it, test, polish it, make drawings, animations, gameplay, menu... a lot of things, probably by one person or a small team, with no garanty of success or recognition by the audience
