Update #15

Hey Peeps, Here's the latest bunch of fixes and tweaks. - I've fixed the 'fullscreen is black' issue. It seems the Windows 10 Creator update causes problems with Java based games. - I've gone through all the levels and closed all the little holes where you can get you ship stuck. - I've added some new sounds and changed some others. The most obvious are the bullet impact sounds. - I've added little icons to the campaign to indicate which regions unlock weaposna dn ships. - I've added a little improvement to performance. It seems that Gamemaker will still call the Draw event on objects that aren't on the screen. There might be a good reason why it does this, but I've stopped it because it's silly, very silly. - I've made a couple of little tweaks to the ai behaviour, they should now swarm the player less.
