"Kiss Me More" was written by the artists alongside producers Yeti Beats and Rogét Chahayed, as well as Tizhimself and Carter Lang, who both provided additional production, and Lukasz Gottwald.

[4][5][6] Looking back at the success of Hot Pink, staff writers at Billboard observed that Doja Cat had the "innate ability" to produce hit singles, and argued that she was becoming a "quintessential [Generation] Z pop star".

After the album had performed great on the charts, the senior staff at Doja Cat's record label, RCA, believed that they needed to release a good follow-up song that would attain Internet-driven commercial success just like her previous singles.

[25] Doja Cat opens the song with vocals that recall "the gentle airiness of a light breeze", before two crashes of cymbals "act like glue" as they precede the beat drop.

[26] The song is "bolstered" by a "sunny, glimmering riff" and both singing and rap verses which critics noted to spotlight Doja Cat as equal parts singer and rapper.

[30][31][22][32] Jon Caramanica of The New York Times wrote that it "mixes the breeze of lite 1980s funk with the bawdiness of 2020s hip-hop, a juggling act that Doja Cat has pioneered, if not trademarked, by now.

[34] Writing for Teen Vogue, Claire Dodson described the song as "excellent" and "a shimmering ode to kissing [...] with a somewhat melancholy underlying melody that contrasts well with that signature soft-disco Doja beat.

Describing it as "light and uptempo" and deeming it "a masterclass in disco-adjacent pop music", they praised Doja Cat's "terrific job balancing singing and rapping over a catchy riff" with her "snappy flow" and "tongue-in-cheek punchlines".

[43] In an album review for Consequence, Carys Anderson agreed that the song "sums up every layer of Doja Cat’s complex celebrity" with its infectious guitar line and chanted refrain, ultimately making it "a summery summation" of the "hyper-feminine, hyper-sexual, hyper-futuristic aesthetic" of Planet Her.

[69] It features an astronaut (played by American actor Alex Landi)[70][71] who crash-lands and explores the fictional "Planet Her", where Doja Cat and SZA portray seductive aliens who "provide soulful ambiance to his journey."

[72][30][10][73][34] Emlyn Travis of MTV praised the music video, describing Planet Her as "a mysterious, flourishing world filled with glittering oases, calming zen gardens, pastel sunset skies, and blossoming cherry trees that is ruled by two larger-than-life queens".

[37] John Wohlmacher of Beats Per Minute noted that the fact that these "playful goddesses" were more interested in videogames than men shows just how clever the thematic approach to Planet Her was.

[77] During a solo virtual concert as part of American Express's "Unstaged" campaign, SZA performed her verse from the song as well as the chorus usually sung by Doja Cat.

On July 22, 2022, Sony Music Japan announced a remix of "Kiss Me More" was released to digital stores, with Japanese comedian Naomi Watanabe replacing SZA as a featured artist.
