Purrsuit

An iPhone game where a crew of cats raids a fish market.

Client: Purrsuit
Scope: Game design, 3D art, development
Year: 2026
Status: In progress

Jinx, Purrsuit's hero cat, rendered in 3D beside two iPhones: the game's loading screen and a run along the sea floor — Jinx, rendered in Blender, and the game on two phones

A lane runner for iPhone: a crew of cats raids a fish market with the Dog Squad on their tail. Each of its 30 levels ends in a boss fight, and an endless mode follows the fish from the docks to the bottom of the sea and back over the rooftops. I designed it, modelled and painted the heroes, and built it in Unity, with bots that play every level so the difficulty is measured, not guessed.

The film

61 seconds, no sound

A silent film made from the game itself: a bot plays while the game renders every frame.

The run

7 screens

Swipe to change lanes, up to jump, down to roll. Every level has three stars to earn: clear it, pick up three quarters of its fish, and take no hits. A boss waits at the end of each one.

Purrsuit's level 3 starting on the fish market docks, with the district's name and the three star goals over the boardwalk — A level opens with its three star goals

Jinx running with three power-ups along the left edge, a card that says to swipe up to jump, and the super button ready in the corner — Power-ups down the left edge, the super ready to fire

Red screen edges and a ribbon warning that the Dog Squad is on your tail, after a stumble — Stumble, and the Dog Squad gives chase

Big Bruno, the docks boss, charging down a lane while a POUNCE! callout says how to answer, with his health bar at the top — Every boss attack is called out before it lands

Level clear: two of three stars, the fish earned and a button to double them with an ad, with Jinx dancing in confetti above — Level clear: the stars, the fish, and an optional ad to double them

The levels map: three district cards above ten medallions on a winding path, the next level glowing with Jinx's head beside it and the boss at the top — Ten levels per district, with the boss at the top

Level 6's card: Sgt. Barkley waiting at the end with his taunt, the best stars so far, the three goals and a PLAY button — Each level's card names the boss waiting at the end

The tuna toss: jump it, or land on it

A crate chain: pounce, bounce, pounce

Shadow Dash, Jinx's super

A boss fight: jump, pounce, dodge

The endless journey

11 screens

Endless mode is one looping journey through seven places, each with rules of its own: belts and presses on the beat in a cannery, floaty water physics on the sea floor, a shipwreck's hull to run along, and a deep end where only the hazards glow.

The Cannery's place card over a factory hall with conveyor belts, and the journey bar under the score — Each place opens with a card of its own

Can presses in the Cannery with a red, amber or green light over each lane, and a card that reads red dodge, amber roll, green go — Presses on the beat: red, dodge; amber, roll; green, go

Jinx leaping off the end of the pier toward the sea, with fish arcing ahead of him — The dive, off the end of the pier

Jinx running along the sandy sea floor in a fishbowl helmet, kelp and coral on either side and light rippling on the sand — Kelp Shallows: floaty jumps and a fishbowl for a helmet

Jinx running along the side of a sunken ship's hull, under the Wreck's place card — The Wreck: run along the hull

The Deep End in near darkness, lit by Lantern Lou, an anglerfish swimming ahead, with glowing hazards on the sea floor — The Deep End, where Lantern Lou lights the way

Jinx on the back of Barnacle Bess, a whale, with lines of fish leading to her blowhole and a THAR SHE BLOWS! card — Barnacle Bess: fish only, then the spout

Jinx in slow motion at the top of the whale's spout, high over the rooftops at night, with SHOOK 'EM! on screen and the Dog Squad's submarine flipped over below — The spout shakes off the chase, in slow motion over the rooftops

Rooftops at Night: Jinx running across flat roofs under a full moon, among neon signs and city lights — Rooftops at Night, with a song of its own

An endless run ends: NEW BEST! with the score, the place reached on the second loop, the fish earned and two postcards stamped — The result names the furthest place and stamps its postcards

The endless page: a row of postcards, five stamped and two still hidden, above the best score and five medals from bronze to legend — A postcard from every place reached, and medals for the best score

Heroes in 3D

5 screens

Jinx began as a model sculpted in code. A script carries him into Blender to be rigged, unwrapped and baked, and Substance Painter paints him through a script of its own, with no one at the keyboard. The game loads the result: about 47,000 triangles, six looks, four faces.

Jinx in his six looks side by side: Street, Midnight, Gold Heist, Faux Tux, The Evidence and Catch of the Day — Six looks from one model, each its own painted texture set

Jinx from the front, three-quarter, side and back, in his purple hoodie, shorts and sneakers — The turnaround, rendered in Blender

A close-up of Jinx's smug face, beside two more of his expressions: a happy grin and a shocked stare — His faces: one mesh per expression, swapped in the game

Jinx rendered with his painted textures beside the same model in grey with its wireframe drawn over it — About 47,000 triangles, laid out in clean quads

Six painted texture sheets laid flat, one for each of Jinx's looks — Painted in Substance Painter by a script: one texture set per look

A full turn, rendered in Blender

Props and icons

3 screens

The props on the track and the icons in the menus go through the same pipeline as Jinx: built and baked in Blender, painted in Substance Painter. The app icon is rendered from the game's own models.

Twenty-four painted props from the run, among them a barrier, crates, a pufferfish, a goldfish, nets, a cardboard box with a cat inside, power-ups, a jellyfish, a can press and a tuna — The track's props, painted

Menus and the shop

8 screens

Every screen is built in code, in the look of the game. The shop sells looks, never chances: each price is on its tile, and nothing you buy changes a run.
