After playing it on PC, it delivers a stylish and fun experience, though it can become repetitive and ends a bit too soon. If you enjoy fast shooters with a unique visual style, this is one worth checking out.

You play as Jack Pepper (voiced by Troy Baker, who definitely had way too much fun voicing his role), a gritty private detective who stumbles onto a case that goes much deeper than he planned, because isn’t that always how it goes? The noir tone adds genuine charm, blending cartoon humor with a crime-inspired setting. Dialogue, environmental storytelling, and character interactions all contribute to a world that feels cohesive despite its playful appearance.

A Visual Knockout

Mouse: P.I. For Hire immediately stands out thanks to its striking 1930s rubber-hose aesthetic. The black-and-white visuals, film grain, and exaggerated animation give the game a personality that few shooters, let alone games, can match. Background characters, NPCs, and enemies all react in ways that feel pulled straight from early animation, while the action remains thoroughly modern in feel. It’s the kind of bold visual direction that not only defines the game’s identity but separates it from the crowded retro shooter space.

The closest comparison is Cuphead, but Mouse: P.I. For Hire isn’t simply chasing that game’s coattails. It earns its aesthetic through the details: burn an enemy and he crumbles into a pile of soot; use another weapon and he melts away like the Wicked Witch. These little touches are what elevate the game’s visual identity from impressive to genuinely delightful.

Its bold visual direction not only defines the game’s identity but also helps separate it from the crowded retro shooter space. The game does some really fun things, like when you burn an enemy, he’ll turn into a pile of soot, shooting them full of holes or even blasting their heads of, or using another weapon will vaporize off of them, evoking that classic melting animation. It’s the little details that make the game stand out.

A Rhythm of Chaos and Control

The gameplay loop sends Jack into combat-heavy areas that lean into fast-paced, classic shooter design, emphasizing movement, weapon swapping, and aggressive encounters. The arsenal includes a pistol, shotgun, a futuristic firearm, dynamite, and more, each with a distinct cartoon-inspired feel. Jack can also dish out a kick to push enemies away, or land a punch that deals a surprisingly solid amount of damage. When things get too hot, a dash in any direction keeps you in control.

The enemy encounters are designed to keep players moving, dodging, and prioritizing targets. It can border on chaotic when you’re being overrun, but that tension is part of the fun. Each area culminates in a boss fight, and clearing it rewards you with something needed to progress.

Ultimately, it’s a shooter and it can be as hard or as easy as you make, depending on how well you’re able to pick off enemies, and to be honest, the enemies aren’t super aggressive… unless you put it on the hardest difficulty.

Level design mixes linear progression with light exploration, rewarding players who seek out hidden areas, collectibles, and optional paths. Verticality and shortcuts keep momentum from stalling, and each level introduces something new at a pace that respects the game’s length. One standout mechanic: safes and locks that have Jack use his tail as a lockpick, navigating the locking mechanism to crack them open. It’s a clever, fitting touch.

Between missions, Jack returns to a town hub where he can talk to NPCs for leads, compete in mini-games, upgrade his gear, and pin clues to a crime wall that points him toward his next objective. It’s a satisfying loop that gives the action room to breathe.

The downside to it all is that once you start getting into the game, it’s over. It takes around 10 hours to complete, and I know I didn’t find all the secrets in the levels. In doing that, I’m sure I could have extended the time with the game.

Performance

If you’re running a GPU and CPU from the past few years, you’ll have no trouble here. The game runs smoothly and reliably, which is worth noting given it’s built on Unity, an engine that doesn’t always inspire confidence for performance. Fumi Games has clearly put the work in. The game holds up on both high-end PCs and portable handheld devices alike.

Final Curtain Call

Mouse: P.I. For Hire doesn’t reinvent the wheel. But what it does, it does exceptionally well. The gameplay loop of finding clues, speaking with NPCs, and battling through increasingly intense action arenas is fun throughout, and the structure keeps things moving without overstaying its welcome.

The real star, though, is the art style. Cuphead set a high bar for games built around a specific animation era, and until now nothing had come close to matching it. Mouse: P.I. For Hire doesn’t just imitate that achievement, it earns its place alongside it. The 1930s cartoon aesthetic isn’t just a coat of paint; it’s woven into every enemy reaction, every weapon effect, and every corner of the world.

While I totally enjoyed my time with the game, I have two frustrations. The being if you’re a secret hunter, then the game is going to put you in a bit of a bind. Sadly, if you miss a secret on a level and complete the level, you aren’t able to go back unless you start a new game. I hope that this gets addressed, because this is one of biggest faults of the game and will put people off of trying to get all the hidden stuff.

And sadly, the game lasts around 10-12 hours, while the game respects your time, it you leaves you wanting more. For $29.99, it’s still a great value. Mouse: P.I. For Hire is a masterclass in taking tight shooter gameplay, wrapping it in a genuinely stunning visual identity, and delivering something that feels both fresh and nostalgic at once.
