Boku no Natsuyasumi 4

The gameplay follows a similar design. Boku has only 31 days where time passes in real-time as soon as he moves to a new screen. The game consists of fixed screens with pre-rendered environments and a cinematic camera with different viewpoints for each scene. The player can choose how to spend their time, presented as a sandbox environment. Many activities from previous games return, such as bug collecting, sharing family meals, and fishing, while new ones like playing tabletop games, organizing a beetle circus, challenging other children to duels with mechanical toys, and playing the taiko drum are added.

Many scenes offer interaction for exploration, but there's no further purpose. Time advances when a new scene is entered, so it's not possible to complete all content in a single playthrough.
