i think u should look at a walkthough

you can do it by yourself

You can do it

My advice? Use invincibility. Press start during a level, press and hold L and punch in
AXBBY.

well just follow the path when you defeat 2 shadow montsers there should be a gap jump
over it the next one should be a gap as well jump over that the third one is a star that
you made wait until it appears then jump on that and on to flat gorund(well finally)then
there will be two sets of shadow walkers,show bats and shadow ghosts
