That's awesome!
I agree -- anyway that you can make the routine enjoyable (the gamification part) is good in my book. I was doing a bit of the same until it was too hot (FL heat). Since there's a lot of stop and go with the game I would maybe suggest taking a HIIT route with the exercise aka if you see something to catch try a light jog versus just walking to it - that way you can spike your heart rate and really get things moving!
