Program a maze so that no horizontal bars are on a side of the screen, except for one at the top. Hang out at the top until all the monkeys (or as many as possible) are on top of your man. Then tag the monkeys against the near wall. As you fall, keep the action button pressed down and you will retage the monkeys, over and over again, scoring many points.
