This is fun! Some nitpicks, but I enjoyed the idea overall, and I think it feels satisfying to chuck the guys and knock them out.
The music felt a little incongruous with the fantasy theme. It would be nice if you could see through the cursor to be more sure about who you'll select. This one is really subjective in terms of the design, but I think I'd allow panning around while zooming in for more control, although that definitely makes it easier.
