Very nice, a delightful take on the prompt! And congrats on getting Voice Acting!
Gameplay-wise, I don't really understand the boxes with arrows on them, and level 6 is where I got stuck, but was having a good time with it.
I do think there's a slight dissonance between the theme and mechanics by letting the player control the King slightly with the shoot button. I'd be interested to see if there would be a way to have the King shoot automatically. Some of the levels and mechanics would need to be adjusted, but you could then make up for it by adding time pressure with a ticking clock on when the King takes his shot!
