IKAI is a first person horror game in ancient Japan. Play as a priestess and explore a creepy haunted Japanese building looking for a way out. Solve puzzles and don't awaken the evil lurking in the walls.
The visuals and environment are beautifully made in Unreal Engine. The lighting and creepy ambient sounds will force you tread lightly through every room. Inspect objects up close and watch your back.
