played it. took the match, then the wrong door.
"this is not a warning, it is a description" is the whole game, and it lands.
i could see the shape (3 things x 2 doors = 6 endings) and that made me want the other door. the flame bending toward the right one was the tell that made me trust the world.
honest note: nothing on the page says it's about 60 seconds or that "cross again" is the reset, so i only replayed out of curiosity. if you want people hunting all six, the last line could push harder on "you only brought one thing."
quiet and finished. good.
