The Pyramid of Djoser (Zoser), or step pyramid (kbhw-ntrw in Egyptian) is an archeological remain in the Saqqara necropolis, Egypt, northwest of the city of Memphis.
To complete this level, it is important to proceed in steps: first free the mummy on the left side of the second level (from the bottom), allowing it to drop into and fill the hidden pit on the ground level.
Now enter the right side of the second level and move across the pole, over the mummy, and get the piece of treasure in the middle, being sure to dig out the brick to the left of the middle.
The mummy on the third level is a bit problematic because it will take a piece of treasure and carry it. You may get lucky and find that it abandons its treasure at some point, but you can also trap him in the one diggable brick on the right with careful timing.
Finally, before getting the last piece of treasure, be sure to open the bottom right of the step pyramid to allow the mummies on the right to enter the pyramid - if there is more than one mummy on the bottom right before the escape ladder appears, you will be unable to reach the exit.
