Love it, love to see that you're back in action!!
Main complain that keeps me from having fun, is that Miss Thavel feels like she's no-clipping or teleporting to you. Its just not really fair? If you want her to "ambush" the player, maybe consider having her predict where the player will go, and have her wait behind doors? IDK. She just feels like she's cheating right now.
Here's a clip of her magically appearing and killing me through a door.
Love the death animations, they are super brutal and neat.

When she's close to the player she will start quickly opening and closing all the doors close to her, when this happens walk to a direction locking back and you'll see she appearing. She spawns in the exact location of the player but if you don't pay attention she might just spawn without you seeing her. (the only way to evade her attack is dodging right before she attacks). Hope I helped you
