Arrival of Drones

You may now find a new fella in a new encounter added to the sorting facility, a drone!

Initially, it had this annoying behavior of relocating to new spots on the screen when shot, but for now it's been disabled in favor of a more fair fight.

• Added Drone enemy
  • Flies in a random pattern above the ground, occasionally stopping to fire shots;
  • Has 10 health (takes 7 shots to kill).

Another prototype addition is conveyor belts. Currently they only exist in the drone encounter, but may appear later in the sorting facility, usually guarding mixes of platforming and combat sections.
