"Return to that summer with you..." Ryusei returns to the small island of his younger years, where time flows by gently, to spend a fairy-tale summer vacation with his childhood friend who was spirited away.
As a visual novel, the gameplay primarily revolves around progressing through the story by making narrative choices that affect the outcome. Players can explore multiple endings, ranging from a "good" or "true" ending to several "bad" endings, depending on the decisions they make throughout the story. This branching storyline structure allows for a degree of replayability as players uncover the various narrative paths.
Reviewers highlight the game's strong atmospheric and immersive qualities, particularly in its depiction of the tranquil island setting and the fairy-tale-like summer vacation atmosphere. The gentle flow of time and the overall surreal ambiance successfully draw players into the world of the story, enhancing their overall experience.
The game's soundtrack, composed by Fuminori Matsumoto, is widely praised by players as a standout aspect of the audio presentation. The opening theme song, "Star Trail," performed by the character Ginka's voice actress Ikumi Hasegawa, is especially memorable and contributes to the emotional resonance of the experience.
While the game's control scheme, which primarily utilizes function keys, was initially confusing for some players, the developers have crafted an interface that becomes easy to learn and non-intrusive after a short adjustment period. This accessibility and ease of use facilitate a smooth and uninterrupted narrative experience.
