Friendship Meter

The Friendship Meter is a term referring to the variables required to obtain the Orange Menu in .flow.

Explanation
The variables surrounding the Orange Menu revolve around interacting with Oreko a certain number of times. The Meter only counts interactions that were made after obtaining the Diving Helmet.

There exists three states under which the Friendship Meter count can fall.

Eradication—Oreko is not visible anywhere, and only a diving helmet marks her place. This occurs at -30 points and below.

Neutral—Oreko is visible in her respective areas, allowing Sabitsuki to interact with her. This is the default state upon beginning .flow. This occurs at -29 points to 29 points.

Friend—In addition to Oreko being visible in all of her respective places, a transparent version of herself can be found in the Machine Room in the Starry Pier. This "ghost" will lead Sabitsuki to an area resembling the Starry Pier, where the Orange Menu can be obtained.

Changing the Meter
Upon entering the dream world, if the Friendship Meter is below 29 points, one point will be added to the counter automatically.

The meter will increase upon interacting with Oreko. Interacting with her normally, either in front of her house or standing away from her machine in her home, will cause the meter to increase by five points. This can be raised to ten points if Sabitsuki is using the Diving Helmet effect. Oreko will indicate an addition of points when she turns toward Sabitsuki.

The meter will decrease upon hitting Oreko with the Iron Pipe. This will lead to a reduction of the meter by ten points.

During any dream session, Sabitsuki can only interact with Oreko once. Thus, a total of at least three dream sessions are necessary to obtain the menu.
