Honestly, the only difficulty I had was the relatively tight timing of making it "hit" her. Still quite doable, even with max Polypropelyne. Mildly frustrating nonetheless.
I think that another, interaction alternative to stopping her should be doable. Like hitting 4 or 5 levers that are scattered across the room. Would make it much easier for anyone who's going for a "zero fill" run to actually accomplish that.
