What Is That's Not My Neighbor?

In 1955, the Doppelganger Detection Department hires you as the doorman of an apartment building. Every visitor claims to be a resident, but small errors in a face, document, name, or apartment record can reveal a predator.

How to Play That's Not My Neighbor

Compare the day's resident list with identification cards, entry requests, phone confirmations, and each person's appearance. Admit valid residents, deny suspicious visitors, or call the D.D.D. when the evidence identifies a doppelganger.

That's Not My Neighbor Controls

  • Mouse: inspect documents and use desk controls
  • Click and drag: move paperwork
  • Phone and buttons: verify, admit, deny, or contact the D.D.D.

Objectives

  1. Check whether a visitor appears on the resident list.
  2. Compare face, name, ID number, expiration, and apartment data.
  3. Call an apartment when a story needs confirmation.
  4. Admit residents and report confirmed doppelgangers.

Story, Style, and Horror Design

The booth keeps the player physically separated but never fully safe. Repetitive paperwork builds confidence, then a subtle wrong detail forces a decision with immediate consequences.

That's Not My Neighbor Tips

  • Use the same inspection order for every visitor.
  • Never let a familiar face replace a document check.
  • Confirm only after identifying a specific contradiction.
