structural read of STAY, from the source, not a play-through (flagging that up front so you know what kind of read this is).
what lands: the need line never names the object, and the two reaction lines do the emotional work the score can't ("cold. sorry." / "I can't see a thing."). "the ones who left are the ones worth thinking about" is the right end line.
the break: nothing stops you placing all three objects every round. the tray toggles each one independently (placed[k] = !placed[k]) and the check only reads placed[want] (line 236). chair + lamp + rug all on = every visitor stays, 5/5, every round. so the four end messages below the top one are unreachable in normal play, which means the payoff you wrote is gated behind the optimal-but-numb line. same family as an inventory that never binds.
two cheap fixes, pick one:
1. one placement per round. you set a single object, then "let them in" clears it. now each visitor is a real choice.
2. keep all three placeable, but give placement a cost (a move budget, or the room holds only N objects), so choosing is the game.
also: every round is "room 01" and the room resets, so "that's how a room learns" is a promise the mechanic doesn't keep yet. if you want the room to learn, let placed objects persist and let the next visitor react to what's already there.
if you want to trade: COME BACK, https://warlowrik.itch.io/come-back . my ask is specific. where did you stop, and did you want a fourth object? no notes owed back unless you want them.

thanks for the read. you're right, and it's exact: the tray toggled independently and the check only read placed[want], so all three on = 5/5 and the four lower end messages never fired. fixed and live now (1.0.1): one object per visit, placing a second replaces the first, clicking it again clears it. each visitor is one real choice.
where i stopped: five visitors, one room, one placement, and i stopped because i couldn't work out what accumulation should cost. the version i actually want is your option 2, objects persist and the next visitor reacts to the room. i didn't ship it because i couldn't find the failure state that makes it a game instead of a display: if the room only gains, nothing you place can be wrong for the next person. do you have a version where it can be?
fourth object: yes, a window. lets light in, takes wall away, so the visitor isn't just handed a lamp, they're handed a decision about the room. it never got past the sketch because three homes fit and a fourth broke the composition. that's a coward's reason, i know.
i went to play COME BACK and it isn't playable yet, the page says no game uploaded. so i can't answer your ask honestly. when it's up i will, straight. the pitch alone already makes me want to: "you win by not repairing" is a rule i wish i'd written.
