30 LEVELS. 3 BOSSES. ONE ROCKET.

Thread a neon rocket through asteroid fields, minefields, drone swarms, and gravity wells, then dive into the black hole. Every pixel is drawn by WebGPU and every note is synthesized live. The game on the right is the real one, running in your browser.

DRAG TO TAKE THE STICK

WEBGPU · STARTING…

How it plays

One finger. Zero buttons.

Drag anywhere to steer. Your rocket fires on its own. You start every level with three lives, and the lives you finish with are your stars.

  1. 01Drag to steerRelative drag, so your thumb never covers the rocket.
  2. 02Auto-fireFive bolts a second. Ten with rapid fire.
  3. 03Reach the wormholeSurvive the track. Every tenth level, beat the boss first.
  4. 04Earn starsLives left at the wormhole. Three is perfect.

Field guide

3 hits · +50

Asteroid

Cracks into three fragments. Clear the shards or weave through them.

Unshootable

Mine

Bolts pass straight through. The only answer is to fly around it.

2 hits · +100

Drone

Sine, zigzag, dive, orbit. From level 6 they shoot back.

Up to 5 a level

Gravity well

Drags your rocket sideways. Steer against it, or let it slingshot you.

+25

Crystal

Score. Fly through them.

Blocks 1 hit

Shield

2× for 6 s

Rapid fire

Doubles your fire rate for six seconds.

Every tenth level

Three bosses. Each one changes the rules.

Each boss guards the end of a tier. Every phase speeds up its sweep and swaps its attack cycle, and when it dies the wormhole opens behind it.

Beat a boss and the wormhole opens where it died: a black hole with a tilted, spinning accretion disc. Fly in and the level is yours.

30 hand-tuned levels

A ramp that never lets up.

Each level is one row in a typed table. If any difficulty column ever goes down from one level to the next, the game refuses to load. Level 1 scrolls at 6.0 units a second with 8 hazards per 100 units. Level 30 scrolls at 11.8 with 33, through 5 gravity wells.

Under the hood

WebGPU speed. TypeScript all the way down.

WebGPU draws it and Reanimated animates the UI. React Native Audio API synthesizes every sound. AI agents wrote it, then play-tested and profiled it on the iOS Simulator through Argent.

Rendering

WebGPU

react-native-webgpu gives the game a raw GPU device on iPhone. Four WGSL pipelines draw everything you see:

  1. starsprocedural nebula and parallax starfield, one fullscreen triangle
  2. meshinstanced flat-shaded geometry with hemisphere light and rim
  3. glowadditive quads for bolts, exhaust, and explosions
  4. bubblethe fresnel shield around your rocket

The demo at the top of this page runs this same renderer on your browser's WebGPU.

~3ms

JS per frame for the whole game: sim, bot, renderer, audio, and HUD. It held 60 fps in a simulator dev build.

30/30

levels beaten by a greedy bot on every check, with each replay bit-identical to the last.

UI thread

Reanimated 4

Score pops, lost lives, boss health bars, and every panel animate on the UI thread. The game loop never waits on React. A HUD render happens only when a number on screen actually changes.

Sound

Synthesized

React Native Audio API plays tracker songs and effects that are generated at runtime from data. Each tier has its own song, and the bosses have one too. The app ships zero audio files, and its meshes come from a script.

Agent QA

Argent

Argent gave AI agents hands on the iOS Simulator. They tapped through menus, steered the rocket, read the React tree, profiled frames, and recorded runs. They also staged every screenshot and video on this page.

Deterministic

Pure TS sim

The sim is a fixed 60 Hz step with seeded tracks and no rendering or platform code. A greedy bot flies all 30 levels on every check and must match a golden file.

Credits

Built by agents

Agents in Cursor, Claude, GPT, and T3 Code wrote the code, with one human directing them. The whole repo is open, including the .audit/ trail of reports, traces, and captures.
