Chapter 1: The Disappearance

Your adventure starts with a tutorial section where you’ll learn the basic mechanics of the game. It’s essential to grasp these concepts early as they’ll help you navigate the more complicated puzzles later on.
As you explore, pick up the first star that’s clearly visible on your path. For the second star, you’ll find it perched on top of the blue car, so make sure to grab it!
After securing the stars, drop down and head towards the bridge to complete this section of the game.
Mark’s Room
Find the way out of the kids’ room
Make your way to the right and move down the table until you encounter the green army man. Interact with him for some dialogue.
Climb up the shelves on the left side where you’ll find another star. Don’t forget to jump up on the bed as there’s another star to collect there too.
Cross over the bedside table to grab the star resting on the box; it’s your ticket to exiting the room.
Corridor Room

Examine the clues and find the exit
Climb up the ramp on the left to collect a star from the sofa. Be wary of the radio’s interference when you get too close.
Once you have 7 stars, head to the shop nearby to purchase the Max Health Up. Drop down and interact with the basket holding a picture of the boy, then look for the open air vent to drop into the next room.
Laundry Room
Climb over the washing machine and detergent containers, turning on the light as you proceed. After dropping down, head towards the paintings where you’ll find a star.
Put on the hat in this room for a fun easter egg, and don’t miss inspecting the note and flashlight on the floor. Continue climbing over the paintings, collecting both stars, then drop into the sink.
After that, turn left from the shampoo rack and make your way over the laundry basket to exit the room.
This room is home to a robot vacuum that roams around. Be careful and navigate around it as you head up the skateboard.
Find the way to the garage
Proceed up the stools and onto the kitchen counter to collect a heart. Jump onto the coffee table (it will break!) and use it to springboard onto the sofa, where you can snag another star.
Next, climb on the guitar and then to the right for another star. Navigate past the microwave, avoiding open stoves, and head to the vent on the left to pass through to the next area.
Garage
Figure out how to open the garage door
Climb the ramp decorated with missing child posters and head right. Push the plank down to create a bridge, enabling you to cross to the car.
Go over the car and speak to the bus. You’ll find another star past the ore on your right; make sure to collect it. Drop down to gather a wheel from the cabinet.
Return to the bus and give it the wheel to clear the path. Once that’s done, call the garage door to open it, allowing you to exit.
Garden
Get outside the fence to find the boy
Head up the ramp located near the acetylene cylinder where you can find a heart and a star. Now, it’s time to address the dog outside.
Find something to distract the dog
Head towards the back patio, climbing the ramps and passing over air conditioning units. Use the airflow from the last one to propel yourself onto the picnic table.
Head to the back of the garden and use the sausage to get the dog to move and drive through. Go past the sprinklers – avoid them – and then over the white rock formation and then up the ramp to pick up the star from the high voltage box.
Drop down and drive over to the sandbox to pick up another star. Next, go up the slide and over the fence.
Street

Immediately to your left is a shop. You can buy another Max Health up now.
Go straight up and over the pictures and boxes. Go up the no-entry sign and to the right.
Then the blackboard and on to the street. There is a van to your right with a Lithuanian plate.
Get on top of it for another star. Drop down and talk to the blue car.
If you beat it in a race you can get the Forklift key.
Just follow the path around with the green arcs and you should win. It might take you a couple of tries.
Once you have the key. Go to the right side of the street, past the hopscotch area and up the ramp to find a star.
Go up the glass and over the boxes to get another star. Drop down and pick up a star and a heart from inside the pipes on the right.
Back out and go past the open manhole and up onto the dumpster. Drop down on to the wood planks to get a star and heart.
To the left is the forklift. Go to the other side and up the ramp on the right to get another star in the bus stop.
Go back around and to the forklift. Get up on the plank and wait for it to be lifted.
Get on top of the green car to get another star and into the school bus.
Dream
Play the piano to wake up
Go straight down and up the ramp to the S ramp. Go up and through the seesaw and drive over the piano and pick up the star.
Find the boy’s photo and wake up
Keep going, pick up the star and at the end you will find the photo to wake up.
