Spectacular. On a technical level, Deviser has superb voice acting (always a mark of talent to have character voices with filters and have them still able to be understood), and sound design: there are sounds in Deviser I've never heard in an audio drama before, and they're all incorporated seamlessly into the flow of the story.
And the story itself is absolutely incredible - full of twists and turns to have the listener second-guessing, but also a beatdown's worth of emotional gut punches. A really fascinating insight into the nature of parenthood, survival, and what it means to be human.
