Wooow this was cool! Especially the snappy sound design combined with the 'primary gameplay loop only'-gamedesign. Had a great time playing this one, and I think it fits into the jam them very well, too: like you say, saving the drones isn't that useful anymore at some point.
One thing I would love to suggest is that the lack of art (which isn't a huge problem, of course, this is a jam game and you focussed on the gameplay and did that very well) makes it kind of hard to 'care' about the drones, which kind of undermines the way this game fits into the theme. If they were, say, humanoids or something, that would go a long way with helping the player understand what is going on. Now the color coding of the player/drones/enemies suffices for gameplay ends, but just a slight tweak from programmer art to very basic character design would do a lot, I think!
