This page of the Little Nightmares 2 guide contains a walkthrough of the second part of the game: the Orphanage. In this section here we have described all the interactions you need to do to get to the Orphanage.
The chapter begins with you coming to the city. Your task is to go to the orphanage.
At the beginning, you need to head to the right until you reach the first puzzle.
However, you will see a street with nothing worth your attention. Run to the right and jump through the window to get to the next part of town.
You'll get to a bar that has a lot of clothes in it, but nothing you can interact with. You can't jump onto the bar or look behind it.
Keep walking to the right to get to the next section. There is a hole in the wall that you can squeeze through.
You will pass a pile of destroyed TVs. There's nothing you can do with them, just get closer to the wall on the right and jump into the hole with the help of Six.
The TVs puzzle
At some point you will reach a room with huge holes in the floor. You have to do your best to get to the top.
Jump on the destroyed TV located on the right side.
Jump from the TV to the loop and grasp at it tightly.
You have almost reached the end. Just swing around on the loop and hit the TV on the left with your feet: you have to do everything to make it fall down.
When the TV falls down, it will lift you to a higher floor. Set the loop swinging and jump onto the ledge on the left.
Once at the top, you must turn left.
You still need Six in order to move on. She will be waiting for you on one of the TVs. It's pretty simple. You have to push the TV lying on the boards so that Six can access the higher floors.
Six will immediately run back to lend you a hand. You must run up the stairs, speed up and grab her hand. This is the only way to jump to the other side. If you fall down, you will have to repeat the whole sequence all over again.
While you go forward, you will have to jump over a chasm. If you fall, you will die right away.
Leave this room by squeezing through a narrow crack in the door.
Immediately after squeezing through the door, you will see a brightly glowing TV. It will draw Mono's attention. You must get close to this object or you won't be able to move on.
Put your hand on the TV and adjust the broadcast so that the picture is as clear as possible.
Once the picture is set, you will find yourself in the middle of the broadcast. Try to run directly to the door. Even though it will keep moving away, you can't stop running.
At some point you will be thrown out of the TV and Six will be right next to you.
Entering the orphanage
When you leave the broadcast, you need to go to the window. It will get you out of the building and into the next part of town.
Your next task is to pull the trash can away from the fence. There is a hole right behind it: you can get to the orphanage through it.
There are several objects in the playground that you can use. You can swing, but it won't affect the game in any way. Six won't be too eager to play with you.
Six will be interested only in the bench, standing to the left of the trash can. When you approach the bench, Six will simply sit on it and wait for your move.
Once you have already explored everything in the playground, you need to go to the right corner of the area. There is a bed sheet hanging there that you can climb.
