Hint: Extra lives: Use the following trick to earn up to nine lives. In
level 2 (Pipes), keep shooting the sleeping crabs which never
move. At 50,000 points, you will get one bonus life. Repeat for
more lives. You can do the same thing in the fire level by getting
the spitting can and shooting the fire continuously.

Hint: Skip World 3 Stage 1: You can skip most of World 3 Stage 1 (rooftop). The
first hole that you encounter (and leads to most of the stage)
is too big to jump over. However, a leaf flying from the left
side of the screen to the right can carry you across the hole.
