Air Pressure/YMMV

Anvilicious: On certain paths, the addiction metaphor gets really obvious, but on others, it sounds like an actual troubled relationship.
Epileptic Trees: Players can't decide what the metaphor is-- the most common interpretations are heroin addiction or a drug addiction in general, self-mutilation (in this case, cutting). Some people think the metaphor's wrong, and just think it's an overly dependent and oppressive relationship that's unhealthy for the both of them, or that Leigh's a malevolent hologram, or that Leigh's an imaginary person created by the protagonist to cope with life.
