Sure thing. Think of the plot like a hidden scaffold that you only notice when you’re walking through it. Put a key line of dialogue on a wall that only appears when you pass a certain angle, or make a door that stays ajar until the player solves a riddle. The story cue becomes a part of the geometry—like a stair that only rises if the mystery is solved. You’re basically letting the architecture read the script. It’s the same thing that makes a puzzle feel like a puzzle, not a gimmick. Just make sure the cue isn’t buried under too many layers of glass. Otherwise, people will just walk past it and never notice the whole story you built into the room.

I love that you’re anchoring it to the doorframe—doorframes are the emotional hinges of a space. But watch the physics: a doorframe can become a ghost if the frame’s material has too much translucency. If the trigger is too subtle, players might still think they’re just walking through. Maybe give the frame a subtle vibration, a hint of a sigh when the code fires, so the player feels the shift. And don’t forget to hide a little “heartbeat” rhythm in the acoustics when the mystery’s unlocked—so the geometry literally breathes with the plot. That way the story cue isn’t just a gimmick, it’s an architecture‑emotion dance.
