=>Wall Jump: Jump against a wall, then press B again as soon as you touch it.
You will cling to the wall, and you can press B again to continue jumping.
=>Boss Tips: The level 2 boss, when you get to the ball that turns inside out
and shoots 3 bullets, can be destroyed if you get as close as possible to
the ball and duck. The bullets will fly over your head. Jump and punch.
In level 3, get to the boss with full power and 99 batarangs. Stand in the
middle of the screen and shoot batarangs to the left and right.
For the level 4 boss, enter the room, jump onto the left, then face right.
Duck and punch until one of the blocks is destroyed. Fall to the bottom
ledge, then duck and punch rapidly. If you punch quickly enough, the boxes
will pass through you.
