REMIMORY has delayed the Early Access version of the anime-style survival adventure game Castaway Diary: Portal to the Unknown Isles from its previously planned 2026 release window to 2027. The game will be available for PC via Steam and will support English, Japanese, Korean, Simplified Chinese, Russian, and Traditional Chinese languages. The development team apologized for the delay and promised to return with an experience worth the wait, while continuing active development and communicating closely with players through their Steam Community Hub.
