The haunting death rattles of the cartoon rats in Mouse: PI for Hire will stay with me forever

Traditional animation often defies the finality of death, transforming the end of all things into a slapstick, reversible gag. However, after spending time with the demo for Mouse: PI for Hire, an upcoming first-person shooter defined by its monochromatic, rubber-hose aesthetic, it appears developer Fumi Games has a more macabre perspective. Mortality is messy in this world; rats convulse and gasp as they drown in their own ink—or perhaps it’s blood—assuming they haven’t already been decapitated or reduced to ash. This visceral violence creates a jarring, fascinating dissonance against the game’s whimsical visuals. If the preview is any indication, this contrast is precisely what defines the experience.

The narrative justification for this rodent-on-rodent carnage is, ostensibly, the greater good. Players inhabit the role of detective Jack Pepper (a groan-worthy pun on the cheese) as a search for an old acquaintance entangles him in a web of institutional corruption and the delusions of a fringe scientist. The demo drops players mid-investigation as Jack infiltrates a clandestine laboratory, only to be ambushed by hired goons and mechanical sentries modeled after the scientist’s former flame.

In its current state, Mouse: PI feels like a curated checklist of modern action staples:

• Overwhelming swarms of enemies that serve primarily as cannon fodder.
• Rudimentary environmental puzzles to pace the traversal.
• Hidden collectibles tucked just far enough off the beaten path to encourage light exploration.

While the moment-to-moment gunplay is familiar, Fumi Games’ absolute devotion to recreating early 20th-century animation prevents it from feeling stale. Exploring the lab is akin to wandering through a vintage 1930s short; the attention to line work, texture, and character expression is masterfully executed. This charm extends to the weaponry: a shotgun that physically buckles under its own explosive force and a pistol that sways to the rhythm of the score. More fantastical options, like an acid gun that melts foes down to a pair of blinking, resentful eyes, lean further into the surreal absurdity of the medium.

The demo’s boss encounters—the aforementioned robotic girlfriends—provided a much-needed spike in complexity. These fights demanded precise timing and thoughtful weapon selection, offering a refreshing break from the repetitive task of clearing hallways. While the thrill of mowing down mobs with a rifle is undeniable, the rhythmic, intricate dance of these larger encounters suggests where the game’s true potential lies.

The marketing for Mouse: PI for Hire promises a “noir-fueled detective story” with investigative depth, a claim that currently leaves me somewhat skeptical. The demo focused almost exclusively on traditional shooter mechanics, offering little in the way of sleuthing. Furthermore, the limited dialogue present—specifically an overextended joke regarding the pronunciation of a character named Igorrr—felt belabored. While cartoons often rely on repetitive humor, this specific instance felt more like a missed beat than a clever gag.

Ultimately, I’m left wondering if Mouse: PI for Hire is leaning heavily enough into its distinct identity. It is at its best when it fully embraces the weirdness of its animated roots, rather than adhering to standard shooter tropes. Despite these minor apprehensions, the sheer stylistic ambition of the project is enough to keep Jack Pepper’s monochrome mystery on my radar.
