The album received mixed reviews from critics. Jonathan of Pulse Nigeria reviewed Burna Boy's album On a Spaceship, expressing his opinion that the album fails to show artistic growth. According to Jonathan, while Burna Boy's talent is undeniable, the album lacks the direction and innovative spark that was present during his time with Aristokrat Records, particularly due to the absence of producer LeriQ. The album features a mix of good tracks like "The Realest," "Rizzla," and "Soke," but overall, it feels "safe" and doesn't push creative boundaries. Jonathan also noted that the collaboration with Wizkid on "Single" was particularly disappointing, suffering from poor production and mixing. Ultimately, he rated the album a 3 out of 5, describing it as "worth checking out" but not groundbreaking.[10] Oris Aigbokhaevbolo of Music in Africa, in his review of On a Spaceship, describes the album as Burna Boy's response to the industry's failure to recognize his previous work, particularly L.I.F.E. He observes that while the album starts strong with tracks like "Oluwa Burna," it quickly descends into "a blur of average tunes," largely due to the absence of producer LeriQ. Aigbokhaevbolo views the album as "a kind of vengeful poetry" aimed at those who overlooked Burna Boy's earlier achievements. This approach, he suggests, results in a deliberate underachievement in the album.[11]
