Really cool take on tower defense and creative use of the theme as well. The gameplay was easy to pick on and kept me engaged by flipping between clicker elements and turret placement. There was some interesting choices to be made too. At first I was placing my turrets close to Earth, but their aim kept lacking behind the fast aliens. I soon figured that it was better to setup crossfire with placing some of the turrets far away from Earth. felt pretty good about that.
