Earth Defender

Oh this works really well, didn't expect it to play very interestingly when I saw the concept but I am positively surprised.
The COMs seem smart and like they have some tactics, though maybe that's just their ability to easily dodge because of the scattered shots and your own very large hitbox, but the way it's achieved is unimportant, important is that it works well

It does kind of happen that you can very easily hit the defender when you have few ships left in the middle, but it doesn't always happen so it still keeps the tension of having only few ships left.
