This game has not only intersting gameplay and brilliant story. but also symbolism (Definitely more than love story).
Interesting feeling like something dark inside me, that I that I identify with sometimes is being destroyed and cleansed with light power. Dark Queen cuddling fallen hero looks for me like absorbing something with her heart. After defeat of darkness, inner light leaked through heart. And then final strike with sword (sword looks more like spiritual, rather than just weapon).
