Collect all (4) items on the stage than you can go to the next stage! There are 4 stages. When you collected all the items on all stages you must return to the chest (on the first stage). Open it. Than you can go to the last stage to free the princess!
I have collected 4 items (key, armour, bag, potion), but I still can't get down the stairs. He just walks right over them. I'm using FA-UAS with A1200 standard settings.
