"Rescue" was well received by most critics. Kat Bein of Billboard praised Jane's vocals, writing that they added the "perfect amount of not-so-distressed damsel to its skater-kid cuteness", and described the song as being laced with "authentic swirls of pop punk and metal."[3] Dancing Astronaut's Jessica Mao stated that the song "embodies the complements of old and new talent lending a hand to each other", later finishing his review of the song by writing that "Zeds Dead and Timmer have given the all-familiar dubstep anthem a refreshing makeover in their collaborative efforts on "Rescue.""[4] Writing for EDM.com, John Cameron wrote that the song was once that "exhibits a seamless blend of both of their signature sounds" and praised the song's mix with its vocals, stating that the "catchy melodies intermingle with Jane's vocal in such a way that the song has plenty of utility on festival main stages and radio airwaves alike."[5] Matthew Meadow of Your EDM called the song reminiscent of Zeds Dead's 2014 debut album Somewhere Else and a mix between the duos previous songs "Lights Out" and "Stardust", later commenting on the song's mix of the respective artists style, writing that "Delaney brings her own vibe to the release with her instantly recognisable voice, and Dion Timmer adds a little weight to the drops, but this sounds like a classic Zeds Dead tune as much as it can be."[6]
