Level 131 has three known sections at the moment, given the names The Forest, The Farm, and The Dirt Path.

In The Forest…

The floor is made with not-so-high grass

1. "made with" could be substituted with "consists of"
2. You could specify the grass height (e.g. ankle-high or knee-high)

In the Farm…

initially 50 meters long, but eventually acquiring a bit more than 3 miles

Can be clarified using more specific language (what do "initially" and "acquiring" mean here?) . As of now it's a bit confusing to understand.

the house
The house
the house’s
the house

It's repetitive. Try replacing some instances with the word "it" or omit it entirely (e.g. "one of the house's outlets" -> "an outlet").

In Entities…

Too many sentences start with "The entity". Again, try replacing some instances with the word "it", or find ways to omit it entirely.

The "The other entities of this level are:" section need not exist, just list off the rest of the entities. (i.e. "Other entities like … … also reside on this level.")

Hope that helps!

Level 131 has three known sections at the moment:
The forest
The farm
The dirt path

I don't recommend this, it affects the appearance.

Section 1- The ForestYou can add two plus signs

before it to make the title larger, for example:

Section 1- The Forest

(even if they do not enter the house).

This paragraph can be annotated.

Suggest adding some correlation to the three regions and describing the main body more.

I think that after solving these problems, this article is qualified. I hope my suggestions can help you, have a pleasant writing experience! (Note: My native language is not English, I use a translator, and I also use a translator to read articles)
