Treehouse Area

The Treehouse Area, otherwise known as "Construction in the lake", is an area in Black Space. This area is the fourteenth area the player can enter in Black Space. This and every room that follows is optional.

Overview

This area looks a lot like the construction sites in Deep Well but grey. There's five platforms that go up and to go from one to the other you have to climb ladders.
The bottom platform is surrounded by water. On the second platform there's a bed to rest on. And at the very top platform there is a treehouse with Basil next to it.
Basil will start to follow Omori after he talks to him. After descending two platforms an elevator will show up. In the elevator, is a key. The player can now choose from several destinations.

Once the player has picked an destination, the doors will close. After a while, Basil will try to confess something but the doors will suddenly open again before he can start talking properly.
While the two walk out of the elevator, Basil becomes stuck in the door. The door will forcibly shut and sever Basil's head off.

After this, red hands will spawn. Coming into contact with them will teleport Omori back to Black Space.

Treehouse

Going into the treehouse will show you a heavily distorded version of the real life treehouse found in Sunny's backyard. Interacting with the various objects will only show you short, one letter words describing the objects, such as "toys".

Looking at the calender, it's revealed that it's summer.

Alternative Entrances

• On the last day of the Hikikomori route, the player can interact with the broken elevator on the right of Mr.Jawsum in the Last Resort. This will teleport Omori into the elevator.

Differences

There's a few differences compared to the normal version found. Omori starts out in an elevator. When prompted, the player can only choose to go to Black Space. Backing out of this will bring you to Black Space anyway.
In the treehouse, the cut beta character "Empty Friend" can be found. Upon interacting with it, the screen will distort itself and it'll vanish.

Quotes

Basil: "Ah... Omori! Is it really you? How did you find me?"
Basil: "Are Kel, Aubrey, and Hero here too? I've missed you all so much!"
Basil: "I'm glad the treehouse is still standing. Everyone worked really hard to make it together."
Basil: "Let's go home, Omori."
Basil: "An elevator? I wonder where it leads to. Maybe it can take us back home!"
Basil: "A-Actually... while we're in here. Can I share something with you? Omori?"
Basil: "Hold on, Omori. I... I think I'm stuck."
Basil: "Could you help me out?"
Basil: "Hnnn... Gggg... Huahhh... O... mori..."

Notes

• Even though it doesn't matter what option you choose in the elevator, one can see the ground of the selected area before stepping out.
  
• One can nap in the bed.

• This removes the flying creature that is located just above the bed.
• The bed's event name in the game files is named "Looping Forest: 270" hinting at a possible (former) connection.

• The elevator will always bring you back to the construction site, no matter what option you choose.
• The tree that holds the treehouse has a white outline.
