That’s Not My Neighbor is a psychological horror simulation game where players work as a doorman in a 1950s-style apartment building — but not every visitor is who they appear to be. With its eerie atmosphere, hand-drawn aesthetic, and tense decision-making system, the game challenges players to spot subtle differences between real tenants and terrifying impostors. Applying SweetFX enhances the game’s distinctive vintage art style — deepening shadows, enriching color contrast, and adding cinematic grain for a more immersive, noir-horror experience. Ideal tweaks include moderate sharpening, subtle filmic tone mapping, and reduced bloom to maintain its unsettling, retro charm.
