Thanks for your feedback! for her dialogue she would say that after she would drew first blood meaning already hit you once with her knife.
The key related issue is new and probably have to do with the logic that i implemented regarding taking key in front of her while facing her. i will tweak the logic so the stuck doesnt happen in the next build.
Thanks yes the animation of the death would be refined more as it seems not really polished.
The bug related with understairway glitch will be patched in the next build.
