20th Century Summer Vacation -nsp--as...: Natsu-mon

In a market saturated with high-stakes, fast-paced games, Natsu-Mon: 20th Century Summer Vacation -NSP--As... offers a refreshing breath of air.

Players assume the role of Satoru, the 10-year-old son of a circus ringmaster who arrives in the fictional rural town of Yomogi for a one-month summer stay. The game is presented in a semi-open world environment, allowing players the freedom to explore the verdant countryside, climb virtually any surface, and engage in a plethora of seasonal activities.

In the landscape of modern gaming, where objectives are often marked by glowing waypoints and urgency is the default state, Natsu-Mon: 20th Century Summer Vacation arrives as a gentle rebellion. Developed by Millennium Kitchen and published by Spike Chunsoft, this title—often discussed in emulation and homebrew circles under the format "NSP" (Nintendo Switch Package) and truncated in file lists as "Natsu-Mon 20th Century... -As..."—is a spiritual successor to the beloved Boku no Natsuyasumi (My Summer Vacation) series.

Game Watch Impress highlighted the sheer scope of the open-world, stating it offers "too free a summer vacation" and that the climbing ability allows you to "jump on roofs, climb cliffs, and go anywhere without detours". However, some players have noted minor issues, such as a low camera angle that can cause motion sickness, or a relative lack of activities during the late-night hours compared to the daytime.
