Not sure if this is a bug or not, but Bloody Mariam instakilled me despite not taking all my health.
Scenario was this:
First time hunting Bloody Mariam, read through the entry but didn't take note that she was supposed to be taken out with the dagger and I thought it was the Dark Mirror instead.
So I was running around to the mirrors trying to use the Dark Mirror, ran into her in the bathroom mirror and got grabbed, but then it caused me to instantly lose and i went into the failed contract screen (got greatly reduced cash rewards) after the animation finished even though it looked like I still had health left.
I was carrying the Dark Mirror, Incense Stick, and the Audio Recorder. I wasn't able to switch to or use the Incense Stick to get out of the grab.
She grabbed me right as I used the Dark Mirror to flash (I pressed F)
Health was full, but Fear was also max as well.
Difficulty was on Easy.
Really enjoying this so far, animations and gameplay is solid and its actually gotten me startled a few times
