I'm not rating this game, because I don't know what to rate it. I don't think the subject matter you chose for this is appropriate for a one week project. First of all, this childhood trauma, is not a phobia. A phobia is an extreme or irrational fear of something. This is a game about someone who was abused as a child. Not wanting to be abused does not equate phobia.
I also am not sure about the kind of message you might send to survivors of this particular kind of abuse.
SPOILER ALERT
Your endings are either suicide, murder, and the final more positive one is touched on so briefly and done so in a manner that the abuser calls the protagonist out for 'running away.' So basically, if a survivor plays this 'game' you will be conveying that their only options after something incredibly horrible such as this happens to them, are to kill their abuser, kill themselves, or run away, which is portrayed to be almost cowardly in the game.
People who have gone through this sort of trauma often do consider suicide, and this game isn't helping stop that stigma. There's a whole culture surrounding this kind of trauma, and it's not a pleasant one.
I understand that there was a lack of development, but I think that there may have also been a lack of empathy, understanding, and a surplus of ignorance.
Perhaps if you somehow extended the slightly more positive ending, and maybe did a little research, it could be a little better, and less triggering.
