Use a superjump to reach places too high for a normal jump. However, you cannot jump straight up (you must be moving forward), and you can only do it if you haven't used up all your megaball.

To execute the super jump, jump while moving towards a ledge you want to reach. At the peak of the jump, shoot the megaball and immediately jump. you will bounce off the ball in mid-air and skyrocket up. This is especialy useful in Tengu Man's stage, where jumping from platform to platform against the wind can be risky.

At the Clown Man's level kick a mega ball into the clown's mouth for an extra life.

Do this after you go in the water area in stage 1. If you have bad health, go backwards and keep going until you find a group of trees with a health between them. Destroy the trees to get the health.
