About the game
Miami Beach, 1992. The Rat King has taken over the city, and the only one who can stop him is Special Agent Kung Furball of the Feline Bureau of Investigation: a black cat in a white karate suit, standing under a red torii gate while the sun sets over a neon sea. Across the tiles come the Rat King's henchmen, one after another, and between them and the beach there is nothing but a pair of paws and good timing. Somewhere down the line a cheese thrower is waiting.
Miami Mice is a side-on brawler with the feel of a retro arcade fighter. You walk left and right across the floor, punch fast, kick hard, and raise your guard when a blow is coming. Everything costs something: kicks hit harder than punches but drain more stamina, and when the blue bar runs dry you cannot swing until it fills back up. The red bar is your health, and the score in the corner climbs with every rat you beat. The fights are cartoon karate, with no blood.
Story mode takes you from stage to stage, with a few lines of dialogue between the fights, up to a showdown with the Rat King himself. If you fall, you can retry the stage, at the price of half your score. Horde mode skips the story and sends wave after wave of rats, each one bigger than the last.
It was made by Christoph Schansky for js13kGames 2025, whose theme was "Black Cat". There are no image files: the fighters are drawn on a canvas and moved by a skeleton of bones, so the kicks and punches bend them smoothly, and the music and effects were composed for the game.
Playing it here
Click Play, wait a moment while the music is generated (the title screen says LOADING), and then click START or HORDE MODE. A short message explains the controls; punch or kick to dismiss it and start. The game wants a keyboard (or a gamepad) and does not support touch, so it is best on a computer. The sound plays right away, so check your volume.

A few things worth knowing
Watch the blue bar. A flurry of kicks looks great until the stamina runs out and you are standing there with your paws down. Mix in punches, which cost less.
Block when you are in trouble. Blocking has its own key for a reason: when a crowd closes in, guarding is better than swinging back.
