I always prefer the keyboard input over the mouse in most cases, but it's just my personal preference. Maybe you can add customizable input system and allow the player to use what he/she prefers more? Sorry I wasn't clear with my comment. I mean it took me time to understand where the drone is going to, but maybe I was just "small braining," I think most people wouldn't have the same struggle as I did ahah. But polishing UI is always good, though :)
