NPR's Maureen Corrigan praised the "big, beautifully written" book for placing a non-romantic relationship at its center, and for taking on the issue of cultural appropriation. Paste recommended readers listen to the audiobook to better navigate "the complex, perspective-shifting format". Wired called the novel "utterly absorbing", and The New York Times Book Review referred to it as "delightful and absorbing" and "expansive and entertaining". In a review for The Washington Post, Ron Charles wrote favorably of the book's moral complexity, and related its Shakespearean title to the generative possibilities inherent in gameplay. Publishers Weekly called the novel "a one-of-a-kind achievement". Kirkus said the novel is "ure to enchant even those who have never played a video game in their lives".

According to Zevin, she also drew inspiration for her main characters from actual game designers, including Ken Williams, Roberta Williams, John Carmack, and John Romero. Zevin has said that some of the fictional video games in the book were inspired by real-life games and events, such as the fictional video game Solution, which was "a take on Train", and the fictional video game Pioneers, which reflected her own feelings about playing Stardew Valley. Over the course of three decades, the relationship between two friends, Sadie Green and Sam Masur, changes as they develop a Japanese-themed game that draws critical attention. Tomorrow, and Tomorrow, and Tomorrow is a 2022 novel by Gabrielle Zevin.
