Two rooms now. The boiler, the library, and the rest of the house are still being fitted. Your flags are kept.
Click hotspots. A selected item becomes the cursor inside the frame — then click a hotspot to use it. Select two pocketed things to combine; one glides into the other (lantern + matchbox). Drawers and doors swing open and closed. Esc or a click outside closes popups. Nudge names the next flag; it does not brick the house.
