I can't believe how fun a glorified screensaver can be. I put quite a few hours into this!
Some feedback:
-Sometimes there is a lagspike but it runs great otherwise.
-I don't like how 7 miners in mandatory to progress with building stuff. At least let me get rid of them so I can have a build without them
-Ballista is pretty much mandatory and the only thing you need as it is the only thing good with dealing bases and has very high damage. Maybe it should be more anti-base focused or give homing upgrades to others.
-Lasers could have an upgrade that makes them anti projectile focused at the cost of damage. In the postgame it is the only semi viable AA
