I played this games some years ago, it is about a girl, who wakes up in a house on a riverbank and she cant remember a thing. The game was very creepy, with some horror elements, and she fought using a sword. I remember the final boss was her mother or stepmother. I cant remember the name, but it was the same of the protagonist, something like Anita or Alita.
Update: i don't love this game anymore lol. After the first two acts imo it skips too many plotlines and loses its vibe. But it has a great setup at the beginning and worth playing even for that part.
