it´s so easy killing the Pao-Kai, I wonder why there´s so much people having problems killing it. The 7th level is much more harder, but I find no info about where I should find my backpack, I´ve searched every place, also I can´t escape the giant worm and can´t find the exit of this chapter

Stop spamming ok?, thanks.
One advice: try to play the game properly, instead of cheating. The giant worm is after the scene where the Orcs have stolen your backpack so you have to find it back.
