Punching Boxes

You're a fighter with very little money, and since you can't afford to train at the gym, you train by punching boxes! You have to tap the edges of the screen to punch and destroy the boxes, and be careful to avoid the sharp wood on some of the boxes, or you'll get knocked out! Also, remember there's a time limit, and you have to punch holes to earn extra time. So, punch as fast as you can and earn more points!
