user_prompt: ## Instruction:
  You enter a large area divided into multiple zones and rooms with distinct features. The map consists of an entrance zone, a zone 2 that is separated with a river, a third zone further ahead (zone 3) also separated, and two smaller rooms adjacent to the back of zone 3 separated by shield walls: the left room and the right room. Shield walls do not block passage but destroy any cubes that come into contact with them or destroy any open portals when a player touches the shield. 
  
  In zone 2, you’ll find a button. The right room contains a cube.
  
  The left room in zone 3 has a laser source and two laser slots: one in the front and one in the back. Various blue paths, activated by buttons, allow movement across the zones. Zone 2 contains two laser slots that need to be activated as shown in the images. The exit door is located in zone 2 and requires activation of the final laser slot to open.
  
  Below is a candidate solution:
  Step 1: Enter the room.
  Step 2: Shoot a blue portal on the wall above the entrance and an orange portal on the floor.
  Step 3: Go through the orange portal on the floor and while falling down from the wall, shoot a blue portal where you would land.
  Step 4: This throws the player over into the second zone. From there, go through the shield wall where the button is. Shoot a portal next to the entrance and one in the wall next to the button.
  Step 5: Go collect the cube and bring it to the button in the second zone and place it on the button.
  Step 6: Walk across the new blue path from zone 1 to zone 3 that was activated with the button press.
  Step 7: Press the small button in zone 3 that activates a blue path to go back to the entrance.
  Step 8: Go to the back of zone 3 where there are two more rooms separated with shield walls, the left room and the right room.
  Step 9: Enter the left room. Shoot a blue portal at the wall where the laser hits and an orange portal across to where the laser slot closest to the laser source is.
  Step 10: This laser activation removes the shield wall. Walk out to zone 3, cross the path to zone 2. Shoot a blue portal next to the floor button of zone 2 and bring the cube into the left room.
  Step 11: Shoot a blue portal again into the wall where the laser hits in order to remove the shield wall in the left room.
  Step 12: Bring the cube out of the left room into the central area of zone 3 and place it on the floor such that it points on the second (unused) laser slot in the left room.
  Step 13: From zone 3 (outside of the left room) shoot a new orange portal into the wall of the left room immediately right of the laser slot such that the portal directly points to the cube in a straight line and such that the laser hits the cube and the cube redirects the laser to the laser slot. Adjust the cube if the portal does not fit (as no more portals can be shot due to the shield wall that went up after shooting the portal just now).
  Step 14: Once the laser slot is activated the shield wall to the right room is down.
  Step 15: Enter the right room and fetch the cube on the floor and bring it out into zone 3.
  Step 16: Bring this new cube back to the entrance and place it such that it points to the laser slot located in zone 2 across from the entrance.
  Step 17: Shoot an orange portal into the wall next to the entrance such that the laser hits the cube that was placed there to point towards the laser slot in zone 2.
  Step 18: Fetch the cube remaining in zone 3.
  Step 19: Walk across the new blue path to zone 2 with the cube from zone 3.
  Step 20: Place the cube in zone 2 such that the final laser slot right of the exit door is activated with the laser. Problem solved.
