Tag Signal

A portable tag game block that can travel onto other sites with one script tag and a simple event trail.

Tag Signal is live as a PointCast game block.

The game is a quick browser tag chase: move with keys, click, or touch, tag the red runner, and see the play trail update as events arrive. The portable version mounts with one script tag, loads scoped CSS, and keeps the host page mostly untouched.

Tracking is intentionally simple. The widget stores the last 100 events locally, emits a tag-game:event browser event, sends postMessage for iframe/embed listeners, and can forward JSON to a configured data-endpoint when a site is ready to collect analytics.

✦ react local only

Picks stay on this device until a Nostr signer is connected. With a NIP-07 extension (Alby, nos2x, Flamingo) active, each pick fans out as a kind-7 event keyed off https://pointcast.xyz/b/0388.
