It's beautiful dudes. love the artwork and the animation of the foxes especially.
Only thing that doesn't really work for me is the footprints because they don't show a direction of travel (as real footprints do) so they're not much use... and they seemed to be on every path - do they fade with time? But the tracking idea there is really cool and could be very absorbing if tweaked.
...Oh, and there's spelling mistakes in the tutorial - see comment from Daxterapid below.
