A stealth game with an inverted premise: you are a ghost and therefore invisible, but the objects you carry are not, and floating items cause panic. Residents and pets have proper vision cones and daily routines, so the game is about learning those routines, finding blind spots and using furniture as cover.
The loop is watch, plan, move: observe the room from a safe distance while a resident walks their route and the cat plays in the corner, slip into a blind spot behind the sofa, pick the object up, and cross to its destination in the gap between two glances. Get caught in a vision cone and you have to leave it fast. Timing, patience and spatial thinking decide whether the delivery lands.
