Ok listen
I took the time while 4chan was down to theorize autistically about this game and let me tell you what I came up with:
The first chapter contains themes of food, particularly people, or entities being eaten... And birth
The first thing Froggy says to ENA is that she's "late", and we then find out that the boss isn't even born yet by the receptionist who also, in the same sentence, tells ENA she is late, as if the two are correlated
The next thing Froggy tells ENA is that we have to "Aim for the boss' gut" and "Put that dead meat in his place"
What ENA is 'late' for must therefor be the death of the old genie of Horse Door, plans have already been made to inaugurate a new one and the old one must be fetched and cooked
The Shaman, when sending ENA on her journey, tells her she will "-Begin life anew", but that doesn't necessarily have to refer to her own life
I think ENA's work mission is to first facilitate the birth of the boss, who is gestating somewhere, sleeping and dreaming, while she throws a BBQ to cook the dead body of the previous genie, and then feed it to him so that he may grow and fully become the new boss
If this theme follows, then the order of the doors probably also reflects the order in which food is consumed, but in reverse
The Lonely Door represents consumption and expulsion of the food, the journey from searching to be eaten, to ending up in the bathroom, with the bathroom being represented as somewhere one goes alone both in the simple physical practice of using the toilet, as well as the spiritual theme of finding forgiveness and rebirth
The next door will therefor be the crowd door- The cooking and setting of the table, naturally the door fitting with the theme of cooking being the central motif of the game would also be the door suited for Pietro the Genie, who has been spoken of a lot and is said to have "deviant tastes", likely his whole dimension is themed after large gatherings and banquets
The third door, the Horse Door, will be where we find the meat itself, and so it is fittingly represented by a wild animal and the theme of 'fetching the meat' to cook, the hunt
The poster character, the clown, may not be Pietro, but rather this old dead genie whose meat is being cooked, as in any BBQ, the star of the show is the food itself
In the end of this backwards process ENA will have what she needs to nurse an unborn boss to life
