The House is where you will encounter the first victim of the game.
Enter the house and head left into the living room. Here, you'll find a laptop with a password.
Head through the corridor, taking note of the door locked with a chain, and head left to the far door. You can use this to get to the garage.
The switch to the right of the door can turn on the light in the garage.
You'll need to move the chairs to get to the wardrobe. You'll also find bolt cutters hidden in the far right corner.
Once you've finished with the garage, head to the house entryway and turn right towards the kitchen. You'll need to turn the lights on to enter it.
You'll find a note in the kitchen asking Mark to return home before dark.
Enter the room with the piano through the door in the kitchen.
You'll see a note from Mark's principal on the table informing his parents that he often skips classes.
Head to the chained door and open it with the bolt cutters.
There are three wardrobes in this new room, and you'll need to enter the luminous opening hidden on the left.
While in the alternate relative, head to the second floor, open the door to Mark's room, and enter the glowing opening.
When back in reality, you can't head to the second floor because it's dark. You'll need to use the closet in the basement to enter the alternate dimension.
Head to the second floor and turn on the light in the corner by the stairs.
Go to Mark's room to return to the normal world, and you'll find light upstairs.
Head up and open the nearest door to read the funeral notes on the pedestal, surrounded by flowers.
In the next room, there is a note on the table that will inform you of the death of Mark's brother, Kenny.
Leave this room and head into the bedroom on the left, where you'll find a note in the cabinet.
Go into Mark's room and find his diary informing you that he and his friends mocked Annika constantly.
Leave the room and follow Annika to the piano room.
You'll see a door to the restroom. Enter and carry on walking until you see Mark on fire. Look for more evidence before deciding Mark's fate:
Note in the kitchen
Note in the room with the piano
Note in the office on the second floor
Note on a vase of flowers in a nearby room
Note in a drawer in a bedroom, in a drawer under the TV in the far right (the most crucial note)
Note in the bedside table of the bedroom next to Max's room.
Head back to Mark, where you'll see a person in a chair.
Enter the restroom and decide whether you will forgive or condemn Mark for his actions.
Once you've decided, leave the room, go to the end of the corridor, and turn back. You'll hear the lights go out.
The final door on the right hides a bright doorway, which you can now enter.
