Man I loved this game I watched Markiplier's video and the improvement this game had in just one week is amazing! I have some suggestions.
1-I saw one of the suggestions below about she ambushing you behind doors I think it would be nice if you could hear her breathing when she's doing this.
2-When she runs to attack, and starts stabbing you, (I think that's what triggers this animation but I'm not sure.) it would be cool if she pushes you and then starts stabbing, because it kinda looks weird that she stabs the protagonist multiple times and he doesn't try to get away or fall from the pain, it would be more realistic if after the stabbing animation the protagonist pushes her aside so that the player can also gain some time while she's getting up.
3-it may be just me but, the laughs sound a little weird, it sounds different from her voice, also the voice actor that made her voice did an amazing job! It fits a lot with the character.
4-Also, I think that her teleporting behind you it's kinda cheap, it would be better if she actually sneak up on you and when you notice that she's there, she pushes you.
Sorry for my bad English through out this comment.
