That's Not My Neighbor
Release Date: March 11, 2025
Steam
A logic-adventure game inspired by Papers, Please. In That's Not My Neighbor we can play as a porter working in an apartment complex. Our main tasks include verifying people's identities and making sure they're not dangerous doppelgangers. We have a rather unusual choice list - letting them in, denying them entry or sentencing them to die.
That's Not My Neighbor is a production on the border of logic and adventure games, reminiscent of titles such as Not Tonight and Papers, Please. This project was backed by Ignacio Alvarado, an independent developer from Costa Rica, who goes by the pseudonym Nacho Sama.
The first version of the game was released in February 2024 on the itch.io platform, but over time the priority for the developer became the version intended for Steam.
Gameplay
In That's Not My Neighbor we watch the events from a first-person perspective (FPP).
Porter's duties
During the game, we play the role of a porter working in an apartment complex, who sits motionlessly, dealing with people entering the building. Our task is to make sure that we are dealing with our neighbors or their guests, so as not to let one of the dangerous impostors into the apartment building.
Identification of doppelgangers
The game provides us with a range of tools that allow for the verification of the identities of people showing up. In some cases, signs indicating that something is wrong can be noticed without external help - simply by observing a person through a safety window. In addition to this, we can check their documents, verify the apartment numbers they are going to, and also call their owners to check if they are indeed expecting guests.
Decisions and consequences
It's worth putting effort into our duties, because by letting in a doppelganger, we risk not only him infiltrating the building, but also our own lives. On the other hand, by making the wrong decision, we can condemn an innocent person to death.
If we recognize that we are dealing with a doppelganger, then we should call a DDD officer to deal with the offender. In case we are not one hundred percent sure about the actual identity of a person, the optimal solution is simply to deny them access to the building.
Story
That's Not My Neighbor transports us to an alternative version of the year 1955, in which the world has been taken over by doppelgangers. They are beings capable of replicating the appearance, voice, and personality of specific people. Given that they pose a lethal threat, it has become necessary to establish the Department of Doppelganger Detection (DDD) to ensure the safety of citizens.
Game modes
The pillar of the game in That's Not My Neighbor is a story campaign, the course of which is determined by the decisions we make. There are also other modes, including a nightmare mode (subjecting our skills to the ultimate test), a skill mode (where we fight for the best score), as well as a custom mode (in which we design our own heroes).
Graphics
The graphic design of That's Not My Neighbor is maintained in a cartoonish, yet quite unsettling style.
