Hi, I'm the same guy from the plot problem, but now I'm here to pass on a suggestion my little brother gave me, which would be a password display for secret doors, like swiping a specific card, Either a sequence of colors, a numerical sequence, or buttons that you can scatter around the house and, in the right order, open a secret door—he really wanted something like that, or something similar. Because he really enjoys making secret passages and puzzles.
