It feels like a lot of the time she's too intangible around corners, the main room's desk, etc.
When I get the exit key and I try to juke her around that table, she manages to slash or grab me when she's still behind the table and I'm in front of it. Likewise, around corners she'll simply walk through them as if they didn't exist at all.
she also tends to run at random speeds which makes no sense, sometimes i lose her and other times she chases me down a hall and I lose 5 hp no matter what...
also her breaking the glass windows is useless, crouching over it takes no time at all and she never catches up.
I also experienced her intangibility with corners, which is worse because even if you try to take tight turns around corners to get away she can turn even tighter by phasing through it.
