Critical reception
Paul Simpson of AllMusic viewed the album positively, calling it an "incredibly beautiful, immersive listening experience". He felt that the tracks were easy to "get lost in, or maybe succumb to, as it feels like there's no way out", while working "magnificently" as sleeping or relaxing music to calm listeners down.
