Mouse: P.I. For Hire

Jack Pepper investigates Mouseburg with a pistol in one hand and a dairy pun for a name, and somehow the whole rubber-hose boomer shooter still feels like a real place.

You play as Jack Pepper, a private investigator digging through disappearances, murders, and the underground crime circuit of Mouseburg. The game runs as a 1930s-inspired first-person shooter: rubber-hose animation, noir cartoon crime, mini-arena gunfights, bosses, then detective stretches where you chase leads, talk to locals, and hunt clues. Nearly every enemy is some flavor of rat. Bat rats, gun rats, fat rats, buff rats, little rats, the bottle-throwers. All the rats are here.

Mouse oozes charm. Character design, levels, soundtrack, and atmosphere borrow from old cartoons and noir without collapsing into copycat mode. The parody of mystery stories stays funny without turning every beat into a wink. Jack Pepper is a Pepper Jack cheese joke, and yes, it is cheesy. In a cartoon world, that joke still sits inside the fiction. The rubber-hose work is the real miracle: the bounce in the bodies, the gun animations, even the health and ammo art on the HUD. Watching how far this thing came from the first look almost three years ago sells the craft on its own.

Combat is the main meal. Fast boomer-shooter fights, arena clears, bosses, then back to detective work. I played on the hardest difficulty. Bosses and a few cheesy shootouts killed me. The game still plays fair to easy. Gun variety and the loop of mowing down goons kept me hungry for the next encounter, the next toy in the arsenal, the next special boss. Then the high cuts short. You clear a room, hit that flow of movement and weapon switching and cartoon carnage, and the fight ends before the scene earns the spike. I wanted weaker fodder to keep spawning while the special archetypes press you, or one extra wave so the peak can breathe. Balance wobbles too. The James Gun turns into a lawnmower. Other games in the genre starve you of that ammo so you save it. Here I kept finding more. Still, the shooting is fun. Levels change enough that exploration pays off: newspapers, comic strips, upgrade blueprints, baseball cards for a hub mini-game. The world feels lived in between the blood splatters.

The story held my attention without earning a trophy for structure. Three central mysteries braid together as you gather clues and run missions. The scattershot pacing costs you. You can go several missions before you hear anything about the person you started chasing. In one swamp mission I found an item that looked like it belonged to that guy, and I only remembered the thread when Jack said, “Oh so he was here.” A cleaner three-act shape, one big mystery per act, would have helped. The mysteries stay interesting and a little predictable if you watch the evidence and know the genre’s favorite turns. This is not Shakespeare, and a cartoon PI shooter does not need Shakespeare. What Mouse does well is use its own cartoon rules. Crooked cops and goons give way to robots and cultists without snapping the fantasy.

Homages to 1930s pulp and other boomer shooters land as appreciation, not theft. Some jokes and quotes thud. None of them spoiled the run. I wanted more than rodents in the cast; non-rat faces show up as one-offs or rare enemy types. That is a preference more than a broken design. The campaign also runs longer than it first pretends. When I thought I was halfway done, I was closer to thirty percent. The loop repeats and loses some of the opening punch, but I never got bored enough to put it down.

Thirty dollars buys a ten-to-twenty-hour campaign if you chase completion, a fun combat loop, a story worth following, and a look and soundtrack with real identity. That is a steal. When I started writing this, I had it pegged as a good game leaning on great. By the end of the writeup, I am calling it great. Buy it.
