Level by Paal Olstad.

A Doll's House is a big mansion consisting of a basement (floor 0), a ground floor (floor 1), a first floor (floor 2), a second floor (floor 3) and an attic (floor 4). You move between the different floors by way of elevators (teleporters). The elevators are small rooms each with a light bulb, in the hereby map they are marked by green and red arrows.

You start here, on floor 4 (the attic). Pick up the revolver found ahead. The water surrounding it will make you lose its ammo.

Remove this wardrobe sideways. Take the cross in the little room behind it.

Go down to floor 3 here (green arrow), past the death chalice. Leave the gold chalice for the time being.

Continue.
