Setup

npm install

Run locally

Bot mode (one terminal):

npm run dev

Open http://localhost:3000 and choose Play vs Bot.

Multiplayer (two terminals):

npm run dev:party   # WebSockets on :8787
npm run dev         # site on :3000

Then choose Play with friend, create a room, and share the link.

If friend mode stays on "Connecting…", the multiplayer server (dev:party) is not running.
