Cool game. I like the idea of controlling the swarm, just by looking around.
I think since the gameplay is basically searching stuff, this game would profit rom some mechanics of hidden-object-games. If you wanted to implement that, your world would have to get more details and an interesing artstyle, in which you hide objects (enemies for example) on which you must then click, so that the swarm can localize and attack them.
But that's just a thought. I think you got a cool and innovative mechanic running there. :)
