Hi there!
Just to announce that Dogfight 4.4.17 was published by Apple already and made its way through the network. Since now all servers should be back to normal and we can focus on... wait for it... playing!
Next update we'll try to add curve shooting. Meaning, the bullets will have gravity and you won't be able to shoot straight from miles away. It should fall more/less also depending on your weapon level.
We are already working on some other stuff and will probably make a kickstarter video to explain it.
