user_prompt: ## Instruction:
  You enter the map on an elevated balcony with a rail. Concrete walls surround the sides of this elevated area. Down below is the main (center) room, separated by shield walls from three small rooms: a left room, a right room, and a final room that contains the exit door.
  
  In the center room, there is a laser source aimed toward the final room and a small button that releases a mirror cube into the right room. Both the left and right rooms have laser slots.
  
  - The **right room's laser slot** opens the final exit door.
  - The **left room's laser slot** deactivates the shield wall to the left room, but only while it remains activated.
  - The **final room's shield wall** is deactivated when both the left room's laser slot and its floor button are activated (either by stepping on it or placing something on it).
  - The **shield wall in the right room** is deactivated as long as the floor button in the right room is pressed.
  
  Below is a candidate solution:
  Step 1: Shoot a blue portal on the ground floor and an orange one on the wall next to the entrance. Go through the orange portal to arrive at the ground platform.
  Step 2: In the center room, press the small button to drop a cube into the right room.
  Step 3: Go to the right room and step on the floor button.
  Step 4: Shoot a blue portal on the ground in the center room and an orange one behind yourself on the wall of the right room.
  Step 5: Go through the orange portal with the cube from the right room.
  Step 6: Use the cube to redirect the laser to the laser slot in the right room. This deactivates the shield wall.
  Step 7: Go into the left room and step on the floor button (which also deactivates the shield to the final room).
  Step 8: Shoot a blue portal in the wall in the back of the final room. Shoot an orange portal into the wall of the left room.
  Step 9: Go through the orange portal in the left room to get into the final room. Shoot a blue portal on the back wall of the final room.
  Step 10: Go through the blue portal to return to the left room.
  Step 11: Go to the center room, making sure not to touch the shield wall of the left room (which would remove portals). The shield remains deactivated via the laser. Press the small button to create a new cube. It gets dropped onto the floor button in the right room, deactivating its shield.
  Step 12: Walk into the right room. Shoot an orange portal onto the wall inside the right room.
  Step 13: Redirect the laser using the cube (which is placed on the floor button) to hit the laser slot in the right room.
  Step 14: The final door opens. Go through the orange portal in the right room to re-enter the final room.
  Step 15: Exit through the exit door in the final room. Done.
