Fear and anxiety prevail after the darkest tales from Japanese folklore come to life in this first-person psychological horror game. Set in a feudal era, Ikai revolves around the priestess of a shrine struggling to defeat the spirits of her past and her present.
One of the standout features is the requirement to carefully trace Kanji characters within a time limit to seal away the malevolent yokai (spirits) that prowl the shrine. Using the mouse, players must precisely draw these protective seals, as any mistakes will render them ineffective. Many reviewers noted that this seal-drawing task heightens the sense of tension and helplessness, forcing players to confront the threats directly instead of being able to attack or flee.
In addition to the seal-drawing mechanics, the game presents players with a range of environmental puzzles to solve. These include finding and manipulating objects to uncover hidden paths, as well as more abstract challenges that require careful observation and critical thinking. While most reviewers found the puzzles to be satisfying and coherent, a few noted that some later challenges could be overly obscure or difficult.
Although not a traditional stealth game, the experience does incorporate elements of stealth and avoidance. Players must navigate the shrine's corridors and rooms carefully to avoid detection by the prowling yokai, as engaging them directly is not an option. This focus on observation and timing adds an additional layer of tension and challenge to the gameplay.
One aspect that many reviewers praised is the natural, responsive way players can interact with the environment. Instead of traditional "gamey" interactions, the game encourages more realistic actions, such as physically pulling and pushing doors and objects. This attention to detail helps to further immerse players in the game's world and enhance the sense of helplessness, as they must grapple with their surroundings in a more direct and visceral manner.
