# VANTA//RELAY

A neon isometric puzzle game about being your own infrastructure.

The vault will not accept the current you as a power source. Walk onto a lower-case signal node, **anchor** a frozen echo, then use the reset present-self to cross the matching upper-case gate. Each chamber asks you to sustain more impossible versions of yourself at once.

## Play

This project is fully static and has no package installation or build step.

```sh
cd /root/vanta-relay-20260727-095415
python3 -m http.server 4173
```

Then open `http://127.0.0.1:4173`.

- `WASD` or arrow keys: move
- `Space`: anchor an echo while standing on a lower-case node
- `Z`: remove the most recently anchored echo
- `R`: reset the current relay
- `M`: toggle synthesized audio
- `H`: show the protocol card

The on-screen D-pad and buttons provide touch/click alternatives.

## Design

- **Three authored chambers** — from one echo to three simultaneous signal witnesses.
- **Actual game rules, separate from rendering** — `game-engine.js` is a deterministic, DOM-free state model.
- **Pseudo-3D canvas world** — an isometric grid, extruded null-walls, glowing gates, particles, animated portal rings, and procedural starfield; no images, fonts, CDN, or network runtime calls.
- **Accessible controls** — semantic buttons, canvas label, visible objective/status readouts, and keyboard controls.
- **Optional local progress** — the highest unlocked chamber is stored locally only when browser storage is available.

## Verify

Node 22+ is sufficient; there are no dependencies to install.

```sh
npm test
npm run check
```

The suite covers engine behavior, invalid maps, closed-gate negative paths, echo capacity/undo/reset, authored-map reachability, staged gates, and a static zero-external-asset shell check.
