After you get the lance and open the cage , you will get an artefact , after that go to the red door, you will en up in the room were if you fall you have to fight some monster to get up again, well if you have the stone from the cage and double jump (air hike) you can jump to the other side , is hard butt you will jump eventually. Now my problem is at level 8 , i am in a monsters stomac, and i don`t know what to do , i tried everything.Good luck , and if you find out how to get throw level 8 please tell me.
