Knockout

A boxing ring seen from above: two boxers, blue and red, one round of two minutes. Both boxers always turn to face each other. Walk with the stick and punch with the button. A punch that lands on the other boxer's head scores a point and knocks him back, dazed for a moment and unable to punch. Each boxer has a stamina gauge of four pips: every punch costs one and they refill over time, so swinging at the air leaves you slow when it matters. Bumping into each other pushes you apart. One hundred landed punches is a knockout; otherwise the bell at 0:00 ends the fight and the winner on points is announced. Play a friend, or fight the computer at one of two levels.

Controls: Joystick only. The stick walks your boxer; either side button punches, and holding it keeps punching while stamina lasts. Blue uses controller 1 and red controller 2; against the computer either controller is blue. On the title, up and down choose a line, left, right or a button change it, and a button on START begins.
