While most of the game is pretty easy, there are a few puzzles to keep you going.
The first example of such a puzzle is found in the hallway of apartment 104 when you search for the memories of the dead drug addict Amir. As you come to the end of the flashback, you find yourself running down the hallway, returning to the same room all the time.
This puzzle is in a central room with three televisions - all of them showing the same image. To solve it, you need to change the images on the screen using the desired corridor as a reference.
If you see anything on the screens other than a door with trash cans next to it, it means that you accidentally stumbled upon one of the correct templates.
To begin solving this puzzle, first go to the corridor with the cribs (enter the open green latticed door).
When you return to the main room, head forward so you can see the closed wooden door (this room should have a huge piece of cables on the wall, a door to your right and a hall to your left).
Go down to the left hall and return to the main room.
Now take a look at the monitors and you will see that the trash cans are no longer showing there, although you can still see the main room. Each time you see a different image, it means that you have opened the next section.
In the main room, face the door so that the trash cans are in your field of vision, then turn left and go through the door next to the table on which there is a tablecloth and a TV.
Walk through the door back to the main room and you should notice that the TV screens have changed again - this time they show a flickering light, which means you need to head down the hallway with the light at the top of the wall.
To get into this corridor, turn right in front of the door with the trash can and go forward. There are two doors here - don't go forward, but instead turn right immediately after the light to go through this door.
Check the TV again and it will show you an electrical panel on the wall. This door doesn't quite look like the image on the screen as it doesn't sparkle, so it's hard to find if you don't know where to look.
After facing the trash cans, turn right and keep walking forward instead of turning into the door with the light. Now take one last look at the TV to see a picture of the police interrogation room.
After looking at the screen for a few seconds, you are automatically transported to the next part. After you hear the voice, simply move back and forth with the navigation keys to free yourself.
That's all. You can also find out on our website codes and passwords for all locks in the Observer.
