Milky Way Prince is first-person Interactive visual novel about an abusive relationship with a partner who suffers from Borderline Personality Disorder. It’s a Love/Erotic story, between a guy and a shooting star, that follows players’ decisions. The main themes are idealization and self-annihilation/ sacrifice for the beloved one. During my experience with a Borderline partner, I thought that falling in love with a person with this disorder is like falling in love with a star. You feel like it’s the most precious thing in the universe and the more the love grows the more unstable they become.I think that using this metaphor could be an effective way to indirectly talk about this tough topic. My idea was to create an immersive experience where the player is asked to try to understand the dynamics of this unusual relationship. The character you interact with morphs his behavior/reactions on the player “strategy”. He could set up “rage tests”,“love bombing sessions” or ways to move compassion or make you feel guilty. The plot storylines are regulated by global variables such as “your submission” or “your interest in him”.
