About This Game

OVERVIEW

KISI: The Deja Vu (기시: 더 데자뷰)

KISI: The Deja Vu is a 3D spot-the-difference horror adventure game based on the uncanny feeling of familiarity — known as "déjà vu."

Players become Dr. Hoffman, a neuroscientist, who must find an exit within a perfectly symmetrical, mirror-image space.

STORY

"I've never been here before... so why does everything feel so familiar?"

As Dr. Hoffman, you find yourself trapped inside a strangely familiar space.

Two perfectly mirrored rooms — somewhere between them lies the way out.
Psychological tension builds as your own memory becomes your greatest enemy.

GAMEPLAY

The horror evolution of "spot the difference"

Beyond simple puzzles — the purest form of the spot-the-difference genre, recreated in full 3D space.

Move between two rooms that look identical and find what has subtly changed.

Atmospheric direction designed to make you doubt your own memory.

Face the uncanny nature of a space that seems perfectly duplicated.
