Boku no Natsuyasumi

Boku no Natsuyasumi is an adventure game that follows the summer vacation of Boku, a city-dwelling nine-year-old boy who in August 1975 is sent to stay with his extended family in the Japanese countryside for a month. Gameplay takes place in an open-ended environment where the player is free to determine how Boku spends the thirty-one in-game days of his summer vacation, with few set goals or specific obligations of gameplay progression.
