You want to go west here, but your path is blocked by the disembodied hand in a tank, so go east instead. Your goal is in the section of the Upper Level that includes the broken statue. Go around to the area directly below where you exited the stairs and jump up.

Make your way to the stairs on the east side of the basement and go up. Return to “Find Girls Here” from the other side. When you get to a dead end, you need to jump twice to return to the Upper floor. Go back through the door next to the slab, defeat the enemies that attack you, and continue upwards. Return to the stone slab, go through the door just to the west, and use the dagger on the stone statue. Go through the door and take the ceremonial dagger. Defeat the spirit and pick up the skull, then go back west and use the skull on the stone slab, destroying the slab and opening the door. Continue east until you encounter a spirit with a skull. Follow the trail of blood to a vengeful spirit and defeat the spirit. To the east is another sealed door followed by a stone slab. After the scene, you are now in the location marked “After the Fall”.

Attack (Z) through the barrier to provoke the ghost into dropping you through the floor, following you down, and giving you the game’s first Arrow Scene. Proceed to the point on the map marked “Find Girls Here” to, well, find the girls.
