Fun game! Couple things I noticed:
It seems like the "hitbox" at which a drill glows from hovering over it with the mouse is larger than the "hitbox" for clicking it, leading to frustration when I expect the drill to launch from being clicked, and it doesn't. I suggest going with the larger of the two "hitboxes" for both.
Also, I greatly appreciate being able to turn off most of the auto-launch features to give me full control when fighting anomalies, so you should add the option to turn off the auto-launching drone as well.
