Such an atmospherical experience! And it was a lot of fun at the same time. Soundtrack and lighting nailed the dark, moody experience of night before dawn. In some weird way, it was also optimistic, maybe even soothing, as if the soundtrack itself implied the coming of dawn. If I had to pick one thing to criticize, than it would be the pacing in the beginning. The first two waves are way too easy before the difficulty catches up. But after that, the game is splendid in any regard. Keep it up!
