Nice idea. Best strategy was to stay really close with the clickers. It is really intense for a while, but when you learn the rhythm it loses its charm. It works on any number of clicker, because when they are really close to you they go straight towards the cookie. But I myself can't see any easy solution. Maybe some clickers that go completely random, or have totaly different behaviour, but this was a game jam submission after all. So no worries.
