I did quite a bit of running around and trying to hit a baddie that had somehow gotten himself to a spot that is about midway between standing-height and the top of the PC's jump before realizing touching them doesn't do anything. The controls are very responsive, allowing precise jumps and shots, but I'm left with two big questions: "What is that background music? Is it some kind of remix of MoP?" and "What, exactly, is the A* algorithm doing for us here?" I chalk the second one up to my own ignorance, to be honest.
