Give your partner a whip rope or a stick and have him close first one eye. Now try to reach him first with your feet as he swings and moves himself to either deter and avoid you and you change places and closed eye from time to time. Next close both eyes and work again minding to keep the movement minimal and paying attention to the speed we work in. Breath and note if fear is driving you or you are choosing at which speed to move. The stick drill is also great to do while sitting on the ground and moving in this way.
Keep an open mind and change heights and locomotion as the work requires.
