Rachel Aroesti of The Guardian called the EP "nostalgic" and capable of "shepard[ing] pop into the future."
She praised "Alterlife" as a highlight and called it a "double-speed power ballad, replete with twinkling synths and an industrial guitar riff" and compared it to Grimes' 2015 album Art Angels.
She also compared "Ordinary Superstar" to Britney Spears and Hannah Montana, with the former exerting heavy influence over the EP as a whole.
Saam Idelji-Tehrani of The Line of Best Fit also praised Rina, saying "Although Sawayama's mini-album is one laced with nostalgia, she intelligently uses 90s pop and R&B as a canvas to paint 21st Century missives on internet addiction, alter-ego dependence and the gratification found through web-based validation."
Idelji-Tehrani compared "Take Me As I Am" to "NSYNC-inspired power pop" and "Cyber Stockholm Syndrome" to Butterfly-era Mariah Carey.
