The title positions itself as a high-difficulty, hand-drawn 2D samurai action game for Nintendo Switch, emphasizing precision combat, boss-focused encounters, and a route-driven progression system.
Developers describe Gurei as an unforgiving experience built around exacting melee combat and player choice.
The game centers on Rei, a human spirit bound to a duty: defeat the mystical Kami—entities of nature—and absorb their powers.
Players are free to select the order in which they face these bosses, and the game’s dynamic difficulty system adjusts each enemy’s strength according to the player’s chosen path.
That design means a given Kami can be fought early in one run and serve as a final, more formidable confrontation in another.
Combat in Gurei mixes classic and distinctive mechanics.
Rei’s baseline toolkit includes sword strikes, dodges and aerial options such as head stomps, while each defeated Kami grants a unique new skill.
Those new abilities expand tactical options and can change how players approach encounters—examples cited by the developers include a strengthened dash, weapons that execute weakened foes, and healing-oriented powers.
The studios emphasize player agency: the distinct patterns of the Kami combined with their granted skills are intended to let players tailor strategies and retry encounters with different builds.
Beyond its boss battles, Gurei unfolds in a surreal castle that sits between the human and spirit worlds.
As Rei progresses, she meets characters drawn from Japanese mythology who add narrative color, animated vignettes, optional side objectives and hidden secrets.
The defeated Kami remain part of Rei’s journey: after being absorbed, they accompany her physically and provide running commentary.
Those interactions serve both to illuminate lore and to inject levity or obfuscation—sometimes offering useful hints about mechanics, sometimes adding personality without gameplay benefit.
The launch trailer for Gurei is available on the Nintendo eShop for Nintendo Switch owners to view.
