# Threadline

Threadline is an original, single-player browser arcade game with a complete 150-second loop. Guide a living signal through a star map, stitch twelve gold anchors, and avoid moving voids.

## Controls

- Mouse: steer the signal
- WASD or arrow keys: fine movement
- Space: spend 34% phase energy for 0.72 seconds of invulnerability
- R: restart after a finished run

## How to play

Open the public demo and click **Begin Transmission**. Collect all twelve gold anchors before the timer or integrity reaches zero. Consecutive anchors increase the score chain; touching a pink void damages integrity and resets the chain. Phase energy recharges over time.

## Run locally

```bash
npm install
npm run dev
```

## Design notes

The core interaction combines inertial pointer steering, route planning, moving hazards, a replenishing defensive resource, and a risk/reward combo. Every visual and sound is generated in code. The first session needs no account, backend, API key, or installation.
