Mission Protocol

That's Not My Neighbor is a spot-the-difference horror game set in 1955. You play as a doorman for the D.D.D. (Doppelganger Detection Department). Your job is to verify the identity of tenants entering the building. If you make a mistake, you—and the tenants—become lunch for the doppelgangers.

Core Loop

  1. A tenant knocks and presents an entry request and ID.
  2. Match name, photo, stamp, signature, and date against the roster.
  3. Visually compare face and body to the record; note missing/extra features.
  4. Admit or hit the D.D.D. alarm to deny and report.
  5. Log outcomes; survive the day to advance.

Inspection Checklist

Documents

  • •Name, photo, apartment/office number match the ledger
  • •Official D.D.D. stamp and signature present, date valid
  • •Reason for entry makes sense for their role

Appearance

  • •Eyes shape/size count, fingers/toes/limbs not missing or extra
  • •Mouth, teeth, skin tone match the ID portrait
  • •Hairline/ears/nose align with the file

Behavior/Voice

  • •Answers consistent with their tenant role
  • •Does not repeat mismatched phrases or slip up on names

Modes

  • Story

    Day-by-day shifts with a small mistake buffer and escalating pressure.

  • Arcade

    Faster queue, streak-based scoring, quick runs.

  • Nightmare

    Higher impostor rate, fewer hints, less tolerance for errors.

Fail States

  • ✖Admitting a doppelganger triggers immediate failure (you and tenants are killed).
  • ✖Wrongful denial reduces tolerance; exceed the strike limit to end the shift.
  • ✖Letting the queue stall too long also ends the day abruptly.

Observed Characteristics:

  • ▸Analyze ID cards and entry requests.
  • ▸Spot subtle physical anomalies (wrong eyes, extra fingers).
  • ▸Call the D.D.D. to clean up monsters.
  • ▸Arcade mode and Nightmare mode available.
