The NPC behaviour was a highlight for me. First they try to seem non threatening, then they attack and then then they start running as they figure out they are the one in danger. Also the death loop was one of kind mechanic that I haven’t seen used like this before. Would really like to know more about the lore and how the character is! Their portrait was also amazing! Good work!
I would add something to this game I would maybe make the stab / attack animation more noticeable. Like knife sprite or something. But over all very good and unsettling experience.
