I absolutely adore the styling of the game, super cool, you have a great eye. As another comment says, I had issues with the gun tracking my mouse correctly, I basically couldn't aim at all. Also, even once you die, you're still able to shoot, haha. All the same, I managed to destroy the copter thing, which was cool. I got a message in response, although it kind of seemed like it got cut off? Not sure.
Anyway, really cool vibe, great work.
