This is the narrative apex of what I want out of visual novels. Instead of "check all these boxes to see the ending you want," it's a genuine branching storyline that comes around and asks you why you made those choices at the end. The art is fantastic, delivering a lot of the suspense and horror as the truth of the situation is revealed. The voice acting is also to be commended, especially for the changes in tone to distinguish the Voices and the Princess. And speaking of the Voices, the comparisons to The Stanley Parable are understandable--the first thing you hear is The Narrator telling you what to do--but Slay the Princess pushes that meta-commentary to another level. There is now an Archetype in this story with you. What do you do now?

I may go back and finish the other endings at some point, but the ending that I got in my first runthrough was so satisfying that I want to sit with it for a while. For that same reason, I recommend anyone interested in this game to go in with minimal spoilers and see what they end up with. Just remember to take the warnings at the beginning seriously. It is a love story.
