Island Days is a spin-off from the "Days" series released 3 July 2014.
You play as male protagonist, Itou Makoto, and interact with several female characters and build a relationship with each of them. Moreover, the game also contains a mini tower defence, where Makoto and the other female characters will defend their food supply from wild animals taking it. Similar to the previous visual novel series, each female will have an ending based on Makoto's actions.

All of a sudden, the boat becomes unstable and they all become stranded on a deserted island.
