Please Save My Earth, like early manga series that suddenly become popular for many different manga artists careers', is an illustration of the development and transition of Hiwatari Saki from a novice to an experienced manga artist. The difference in art style between the volume 1 and volume 21 of the manga is quite drastic, as illustrated in the image to the right.

The series features a number of homages to anime and manga throughout the manga.^[1]

Manga volume 5^[2]

Issei's sister Kyoko's character design is noted here as being influenced by Osamu Tezuka and is a homage to classic style shōjomanga artists such as Miyako Maki,Makoto Takahashi, Hideko Mizuno, and Shotaro Ishinomori.

From volume 16 and on, the "Editor's Comments" section was omitted from the English-language adaptation by Viz Media, as P. Duffield, the editor and one responsible for them, was no longer working on the project, as mentioned in the final segment of the "Editor's Comments" in volume 15.^[3]
