PurrFlowThe Liquid Cat

Mizu knocked over a jar of something experimental and is now a living liquid. You never move him. A swipe turns gravity for the whole room, and he flows that way until a wall stops him. You cannot stop him halfway — so every swipe is a decision rather than a step.

Try a room

Swipe, arrow keys, or the pad

One rule carries the whole game

A droplet only ever moves if it can reach a strictly lower cell. That single rule produces falling, pooling in a basin, spreading across a floor and draining through a gap — and it is resolved instantly and deterministically, so a room is solved by reasoning rather than by reflexes.

Turn the room, not the cat

Gravity points wherever you last swiped. Mizu keeps going until something stops him, so you are choosing an outcome, not steering.

He splits, and all of him moves

Furniture divides him into as many pieces as the room forces. What you are really managing is how much of him survives to the exit.

The head has to get out too

One droplet carries his face. However much body is already out, the room is not finished until the head is — and if the head goes down a drain, nothing else matters.

Clearing a room, and clearing it properly

Stars and goldfish are recorded separately, so one run can take the par and another can go and fetch the fish.

Result	What it takes
Cleared	the head out, plus 70% of the body
Two stars	90%
Three stars	every drop, inside the room's swipe par
Goldfish	touch it with any part of him before leaving

Twenty chapters, opening one room at a time

Five hundred and seventy-five rooms — twenty-five in each of the first five chapters, thirty in each of the fifteen after them. Each chapter closes on a boss room: the longest line in the chapter, drawing on everything it taught. From the eleventh on, a chapter opens with one rewarded advert, and stays open for good.

CHAPTER 125 rooms

The House

Turning the room, splitting around furniture, switches and doors, the freezer, the kitchen sponge, drains, spilt water and the hairdryer.

CHAPTER 225 rooms

The Pipes

One-way valves, steam through vents, oil, cat litter and the toy magnet — closing on the washing drum.

CHAPTER 325 rooms

The Laboratory

Acid and laser beams, and the discovery that a block of ice is the only part of Mizu that can stand in either.

CHAPTER 425 rooms

The City

Gutters, crossings that will not wait, litter underfoot, and a cleaning robot with an appetite.

CHAPTER 525 rooms

The AI Factory

Pipe junctions, doors that keep their own time, and a copy of Mizu that reads gravity upside down.

CHAPTER 630 rooms

The Cold Store

Ice stops being a hazard and becomes a tool — a frozen block slides straight, over holes and never through a slit.

CHAPTER 730 rooms

The Foundry

Heat, beams and things that eat him. Freeze to survive the cutting, boil to get through the vent.

CHAPTER 830 rooms

The Vault

Being moved by what is not gravity: junctions, one-way valves, and magnets that will take the head off the body.

CHAPTER 930 rooms

The Sky Deck

Wind from four sides, arguing with the gravity you just set, over sponges that hold what they soak.

CHAPTER 1030 rooms

The Core

The mirror twin, and everything else at once — junctions, timed doors, beams, magnets and ice.

CHAPTER 1130 rooms

The Greenhouse

Sponges and standing water in every room, and litter waiting to cake him too thick to fit through a slit.

CHAPTER 1230 rooms

The Aquarium

Oil he floats on and water that rinses him clean, with valves deciding which of the two he ever reaches.

CHAPTER 1330 rooms

The Observatory

Beams down every sightline. A block of ice is both the shield and the only way across.

CHAPTER 1430 rooms

The Archive

Doors that open on the count rather than on weight, and magnets that reach for the collar bell.

CHAPTER 1530 rooms

The Reactor

Heaters and beams together: boil him to vapour to rise through a vent, freeze him solid to block one.

CHAPTER 1630 rooms

The Canopy

Almost nothing but draught. Fans and valves overrule the gravity you just set, with drains under the gaps.

CHAPTER 1730 rooms

The Depths

Cold in every room. Ice is the tool, water is the way back, and a sponge is the only thing that lets go.

CHAPTER 1830 rooms

The Storm

Wind and heat at once, over doors keeping their own time and junctions that send him somewhere else entirely.

CHAPTER 1930 rooms

The Hall of Mirrors

Junctions everywhere: in one end, out of an end you did not pick — with magnets and drains waiting at the other side.

CHAPTER 2030 rooms

Skyfall

Everything the machine has, on its own clock, all at once. The last boss room in the game.

Seventeen devices, each explaining itself in the room

The first time one does something to Mizu, a bubble points at that exact square with a picture of the device and one line on what it does. It is shown once, ever — and the rules screen carries the same lines for anyone who wants to read ahead. These are those pictures.

Slit

Only free-flowing liquid squeezes through.

Switch, latch and door

Weight opens the door; a latch stays on for good.

Sponge

Soaks up what touches it; turn the room so a wall wrings it out.

Freezer

A frozen block only slides straight — over holes, never through slits.

Heater and chiller

Boils Mizu into vapour, which rises against gravity and slips through vents.

Fan

Its draught overrules gravity in its path.

Oil

He floats on it and rises through it, but never sinks.

Water

One puddle, one unit back — and it rinses litter off.

Litter

Cakes him too thick for a slit.

Drain

Whatever falls in is gone.

Valve

One direction only.

Magnet

Yanks his collar bell and drags the head off without the body — once.

Acid

Takes anything soft; a frozen block rides over the top.

Laser

The beam cuts anything soft, and ice both survives it and blocks it.

Junction

In one end, out of the other.

The twin

A copy of Mizu that reads gravity upside down. It holds switches and blocks beams, and counts for nothing.

Timed doors

One open on even swipe counts, one on odd — the room keeps its own time.

Past the twenty chapters

A hundred-room daily journey

Outside the story and on its own seed, walked in order, with the whole path on screen from the first day — locked rooms included. Five rooms a day, and past that each rewarded ad adds three more. Today's tally resets at local midnight.

Goldfish, and fourteen cats

Goldfish are the currency and cats are what they buy — fourteen breeds, each differing in colour, markings, how round it sits and how long its ears are. There is no sprite to swap: a Ragdoll still behaves exactly like a puddle.

Six colour packs, or a photo of your own

A light pack flips the Material base, the chrome text and the neutral button skin, so the whole app follows — not just the room. Bring your own photo and a dim slider keeps Mizu visible over it.

Twenty languages, right-to-left included

Switchable in Settings, each listed in its own script. Arabic flips the whole interface right-to-left — widgets, date formats and text direction follow the choice.

Pour him out of every room

Unlimited undo, restart at any point, and the room you were in is saved after every swipe — Continue always picks up exactly where you left off.

Fully offline — nothing it does needs a network.
