Castaway Diary: Portal to the Unknown Isles

Castaway Diary: Portal to the Unknown Isles is a bright, casual survival sandbox game following the adventures of girls stranded on an uncharted island. Setting itself apart from conventional grim and tension-heavy survival games, it is designed to offer a relaxed and leisurely island survival life alongside charming anime-style characters—featuring gathering, fishing, and cooking, as well as highly customizable housing, farming, and character customization through crafted outfits. Players can also explore uncharted islands and dungeons on mounts, defeat monsters, and team up in up to four-player online cooperative multiplayer to pioneer the island and conquer dungeons together.
