The story follows Makoto Itou who, along with his various female companions, finds himself stranded on a remote island. While awaiting rescue, Makoto and the others must do their best to survive on the island. The game is split into two main parts, story and battle. The story part follows a typical visual novel structure, in which the protagonist, Makoto, interacts with the various female characters and builds relationships with them. The battle part is a tower defense game, in which Makoto and the girls must protect their food supply from wild animals. As characters lose health while participating in battles, players should be careful to manage who accompanies Makoto into battles. As per many visual novels, the plot can take various courses based on the player's actions, such as who Makoto romantically pursues, or potential deaths among the characters. [from Wikipedia]
