Ah, that's what was happening! I got that she was moving them, but I was never quite certain of where she was (I did peek her running between trees a few times, but would lose sight of her between lightning strikes. Which was cool, but made following her basically impossible for me).
It's a really cool mechanic, I'd love to see you play with different ways to communicate it. The way I moved in your game was completely different to how I usually would in this style of horror game.
<Peer around, see nothing, run as fast as I can>
<See charm, run closeish to it, watch it from behind a tree at what I judged to be a safe distance>
<Creep forward in the dark toward the jangling, lightning strikes, sprint for the charm with metaphorical arms outstretched>
Maybe there needs to be a wide aura around the ghost (fog? visual distortions? skittering insects on the ground?) visible from quite a distance away, even when the ghost isn't. You know she's in there somewhere, but not where... And you know you can only grab the charm when you're in there with her...
Not sure whether that would work! But I definitely think it's worth exploring different ways of communicating the mechanic if you end up working on it post-jam; trying to get an object from a creature that doesn't want you to have it is a far more interesting horror experience than something chasing you and it would be cool to see what you can do with it!
