Each button drives her live through felt-animation (no-cors requests, Felt must be running). One at a time: wait for her to finish before the next. The chest sits at the right end of the primary screen.
Accept items
Walks to a chair already on the floor, or conjures one behind her (dissolve), and sits on it. Hips on the seat: no floating, no sinking.
Stands up off the chair (the chair stays as clutter).
Picks the bottle up off the floor with her LEFT hand (one fades in by her feet if none is lying around), unscrews the cap with her right hand, drinks, closes it, puts it down.
Walks to the small chest, the lid opens, she bends and reaches in; the phone fades in inside the chest and goes up into her hand (no pop), then she puts it down.
Looks around, points, and a potted plant dissolves in beside her with a glowing edge and a sparkle puff.
Same as the Ctrl+Shift+X key: everything but the chest dissolves out at once.
5. Persistence: place a few things, restart Felt (Launch Felt), and they're back where they were.
More props
Another big item.
Conjured into her hand, held a few seconds, put down.
Picks up the oldest clutter and throws it into the chest (or carries it there).
Walks up to the nearest dropped item and kicks it; it rolls and settles.
Events
Headphones on (they come off when the music stops).
Holds a controller for a while, then puts it down.
