The game is largely linear and involves going from point A to B though the expansive environment with multiple obstacles that may induce the feeling of being lost. After some time exploring the player's house, the player is taken to a dreamlike location with a gingerbread house-like hut that serves as a sort of hub level. The house contains a circular door that leads to a new level, surrounded by four containers where "memories" obtained from each level are stored. After the player finds a memory and heads to a tube at the end of the level, they will be returned to this hut.
Story[]
Set in the 1990s, a toddler named David is having his second birthday celebration at his home with his mother Zoey. The celebration is interrupted by a visitor at the front door who is hidden from David, but the story suggests it is David's father Justin, with whom Zoey has divorced and who had remarried with an actress. The conversation is muffled and partly kept from David as Zoey raises her voice, refusing Justin's request to see his child. Zoey's angry tone frightens David, whose fear is presented as blurred vision. Quickly, Zoey returns with a gift, but she doesn't say who the gift is from. Instead, she carries David and the gift upstairs to the child's room, a place of bright, warm colors and streaming sunlight. Zoey briefly opens the gift, but looks at what is inside with a disdainful expression before quickly shutting the gift box. Before the present is given to David, the telephone rings, and Zoey leaves David in the bedroom to play alone. The gift is revealed to be a sentient teddy bear, who climbs out of the box and hides in the chest until David finds him. The bear introduces himself as Teddy. Teddy has a friendly, curious nature. After a few minutes playing together with a music box, a stuffed pink elephant, a story book, and a toy train, they go into the closet, which turns out to be a large, dark room filled with long, dark colored coats. Teddy says that if David gets scared in the dark, he can hug Teddy to feel more safe. Once David holds Teddy, he lights the way, acting like a flashlight. The small adventure is ended by Zoey finding them; she tells David, gently but ominously, to stop hiding from her and puts him to bed.
Later that night, Teddy is taken away from David by an unseen force. David goes after it and finds Teddy inside a washing machine. He unplugs it and takes him out. Teddy realizes that something is not right and that they must find Zoey. Along the way, they encounter a shadowy figure called Harald. The search leads them to discover a slide that takes them to a small playhouse within a cavern that is presumably under the house, and the door found inside it leads them into a journey through several surreal environments, consisting of an underground playground, a dilapidated mansion that has merged with a marshy forest, and a bizarre series of corridors created by hundreds of closets. Teddy instructs David to find four memories he shared with Zoey that will lead them to her. The memories take the forms of four objects: Her pendant from her necklace shown at the start of the game, the music box she plays to put him to sleep at night, the story book, and the pink elephant. Throughout the search, David is pursued by a large, feminine, troll-like monster named Hyda and a creature with glowing white eyes named Heap, who has a coat as a body like the ones in David's closet earlier.
After the last memory is found, Teddy and David try to go through the slide that would lead back to the playhouse, but Heap grabs onto Teddy to stop David from completing the last memory. David hangs over an abyss and Teddy's arm is ripped off due to the weight of David. David then falls into a dark place lit by a series of floodlights. David follows Zoey's voice and sees her drinking from a bottle as she transforms into Hyda (implying that Zoey, Hyda, Harald, and Heap are all the same being) before disappearing. David is left alone in the dark, with window lights coming from up ahead, leading him back to the playhouse. After using the last memory and Teddy's torn arm to open the playhouse's door, David sees cracks in a door that's straight ahead. Once through the door, David is back in his room (having exited through the closet). David heads downstairs to find Zoey crying in the kitchen, with the damaged Teddy in one hand, and an empty wine bottle in the other, which she drops. When David attempts to retrieve Teddy, Zoey knocks David over and shouts at him to leave her alone. She apologizes and tells David she didn't mean to, and that it's too much. David has the option of briefly comforting Zoey should he interact with her again.
There is a knock at the front door that Zoey doesn't react to; instead, she continues crying. When David goes to the door, it opens and reveals a glowing white light. Justin is heard talking to David, remarking on Teddy's broken arm, stating that he can fix him. It is implied that Justin gains full custody of his child after this.
