Ikai is a first-person psychological horror game developed by Endflame, drawing inspiration from Japanese folklore. The game places players in the role of a defenseless priestess, Naoko, who cannot attack the supernatural threats she encounters. Gameplay mechanics emphasize helplessness and tension through slow, precise interactions, direct confrontation with enemies, exploration of a feudal Shinto shrine, drawing protective seals, solving puzzles, and utilizing stealth and evasion.The narrative centers on Naoko, who is left in charge of her uncle's shrine as rumors of a demon attempting to cross into the human world spread. Her usual routine is disrupted by escalating supernatural events, forcing her to confront the encroaching darkness. Ikai aims to foster immersion and a palpable sense of dread by closely mirroring real-life movements and interactions within its uncanny world.
