Considering drugs have brushed my personal life, I should know that drugs and self-mutilation are like parasites that should be cut out, no matter how painful the process.
But.
If you portrayed the addiction as a monster or a maze, it would've had less effect on the player, and make it easier to beat. But you portrayed it as a loved one, making the challenge not for skill, but for emotion and conviction.
THIS is how addicts see it, they don't see it as a danger to destroy, to overcome, they see it as someone close to them, someone who helps them when nobody else will.
Leigh seems to know just the right thing to say and do to unnerve you and make you more compliant, employing everything to keep you with her, at that point I could only tell the difference between the good and bad endings because everyone had put it in their reviews.
Even though I knew I had to get rid of her, I had nearly cried in the "good" ending.
Five stars isn't enough.
