Boxing is an adversarial game where precise control and appropriate responses to your opponent are key. The players have two minutes (around 1200 steps) to duke it out in the ring. Each step, they can move and punch. Successful punches score points, 1 point for a long jab, 2 for a close power punch, and 100 points for a KO (which also will end the game). Whenever you score a number of points, you are rewarded by that number and your opponent is penalized by that number.
