Then go to Charlotte’s room to sleep.
Once you hear the sound, go to the room that was closed for the whole day. Enter the TV.

[ Lv2. Teddy Bear Hologram ]
Congrats! You’ve entered the realm of the little pythian Freya who wants everyone dead.

Following the notes in capital letters will kill Charlotte as they are lies.

Floor 1
Don’t go up, go straight to the room on the right and pull the rope.
It will cause rain to stop.
A teddy will come out trying to kill you, so run to the room on the left and pull the rope here. Go back to the right room and enter the crack in the wall.
Find a key in the kitchen to go forward.

Floor 2
In the next hallway talk to the girl, and look for a rabbit toy to give it to her.
Leave through the door on the right.
Charlotte’ll end up in a room with 4 doors - CAT ROOM, BEAR ROOM, MIRROR ROOM and THREE BEARS HOUSE.

Cat Room
Both cats lie, drink from the right cup (closest to entrance) and only the left fireplace is safe to enter once you’ve drank from the cup.
Inside the fireplace you’ll find a ring.

Bear Room
Take Sci-Fi Almanac from the shelf and a Bronze key from the shelf with a flowers vase and a napkin. Once the bear will attack you, choose the Almanac from inventory and use it.

Three Bears House
Notes suggest you to take some burglar action but you only have to walk around in the rooms and find the Key. The window facing the exit door is the one you need to use.
If you do sit/eat/sleep, the bears will come for you.

Mirror Room
Open the room with the Bronze Key, turn the switch ON, look in the mirror and the secret door will open. Enter it with Silver Key and save your progress.
Choose the Torture Room when caught by the bears.
Enter the TV.

[ Lv2. Silent Film ]
Not all the boxes are harmless.

Password from the door that has a box (it's not floating like the others) with the door knob is 3650.
After you open the door in the main hall, you'll find yourself in the hall with long ladder.
Next password you’ll need is 31221312 (the number of the eyes in the blocks).
Enter the TV once the door opens.

In the TV HALL, enter the same TV again.

[ Lv2.5 Silent Film 2.0 ]
Everything is pretty much the same, except Felix is in the Hall of Knowledge and Charlotte can talk to Frei three times once you find him in the library.
Password for the eye hall - 13223121 (reverse).


[ Lv4. Chaotic Nonsense ]
Welp this dimension is awkward. Did somebody say STEAK?

Go to the Happiness Room. Avoid eyeballs.
Talk to the flower lady that doesn’t lie (i.e doesn’t tell different things every time you talk to her), she’ll ask Charlotte to bring contents of a box.
Go back to main doors hall, go to 2nd door. Take the contents of red box, go back to flower lady - she will give Charlotte a brooch.
You can either do an easter egg quest with pomegranates and go to “Gore Room” or go straight for the door that “glares at Charlotte” and gouge out its eye.
Go to the left door in the hall with clocks.

Maze
Avoid eyeballs. Felix & Charlotte’ll have to get separated so choose wisely.

Tic-Tac-Toe
In the red box, there’s an instruction how to pass the tiles unharmed. Follow the “O”s. In the hall with many doors, you can choose to waste time and look at pretty background textures or go straight to the door at the bottom where you both decide to come back. Actually, there are 4-5 doors in the room that lead to that room (it has the same background as the Maze does).
Go back to the Maze.

If you get Bad End... (Felix stays)
Enter the left room in clocks hall. The timer will start, running away is pointless. You can kill Charlotte before Freya does with scissors in the room with 6 doors.
Then the Afternoon Tea Time event will happen and everything will reset back.

If you get True End... (Charlotte stays)
Go to the middle door in clocks hall and get to the BBQ Room (actually it’s incinerator room but...). Talk to Charlotte then leave together.

[ Lv5. Slaughterland ]

Don’t enter the Slaughterhouse with no windows without a mask!
Find the Executioner masks in one of the houses. Pass is 4981.
Go to the Slaughterhouse with no windows (now the Executioners don't pay attention to you) and find the password to Slaughterhouse-5 inside.
Find a room with a lot of corpses inside the Slaughterhouse-5 and talk to one of them. Then go to the TV room on the same floor.

[ Lv6. The Oracle ]
Enter the last TV in the TV HALL and enjoy the ending.

P.S. Taking the pills is obligatory.
Depending on Charlotte's relationship with Felix you'll see a certain someone in the end in Charlotte's room.

That's all for now!
