Remix of The northwest mall

Use Antics to make my game multiplayer and host it (https://antics.gg) — my friends should be able to join from a link on phones or laptops.

Read the antics docs before you write any netcode — build against the real SDK, not a guess. If the Antics MCP isn't connected yet, add it first: `codex mcp add antics -- npx -y antics-mcp`. No MCP where your agent runs? Read https://antics.gg/llms.txt — the complete SDK and deploy guide in one file.

The game: [point at the game you're building for me, or describe a new one — players, goal, controls].

Integrate rooms + live state sync, and a leaderboard if the game has scores. One known gotcha if the game uses a full-screen <canvas>: give it explicit CSS width/height (e.g. 100%) — `position:fixed; inset:0` alone does not stretch a canvas, and a devicePixelRatio-scaled bitmap breaks mouse/camera math on hi-DPI screens.

Build and deploy without asking for approval along the way, and check the deployed game really works before you reply. Reply with the playable link and anything I should know — skip the play-by-play.
