Game

A mobile-first, responsive, fullscreen 3D multiplayer space game built with SvelteKit, Threlte (Three.js), and Cloudflare Workers + Durable Objects.

Game Overview

Solo Mode: Pilot your ship across the surface of a sphere, convert hostile NPCs into allied satellites, collect power-ups, and survive waves of enemies. A hidden puzzle structure exists within the sphere — not obvious when playing alone.

Multiplayer Mode: As players join, NPC bots decrease. The hidden puzzle reveals itself — players collaborate to align puzzle nodes into a symmetrical structure by converting NPCs and interacting with nodes directly.

Controls

Desktop: WASD/Arrows to move, Mouse to aim, Click/Space to shoot, E to interact with puzzle nodes, Shift to boost.

Mobile: Left virtual joystick to move, Right virtual joystick to aim, Tap fire button to shoot.

Tech Stack

• SvelteKit — App framework
• Threlte — Svelte + Three.js for 3D rendering
• Cloudflare Workers + Durable Objects — Real-time multiplayer (WebSocket)
• Cloudflare Pages — Deployment target

Development

npm install
npm run dev

Deployment to Cloudflare Pages

1. Create a new GitHub repository and push this code
2. Go to the Cloudflare dashboard -> Pages
3. Click "Create a project" -> "Connect to Git"
4. Select your repository
5. Configure build settings:
   • Build command: npm run build
   • Build output directory: .svelte-kit/cloudflare
   • Node.js version: 18+ (set in Environment Variables: NODE_VERSION = 18)
6. Click "Save and Deploy"

Multiplayer Server

Multiplayer runs on Cloudflare Workers with Durable Objects for room-based WebSocket connections. Each room is a Durable Object that handles:

• Player join/leave events
• Position synchronization (~20 ticks/sec server-authoritative)
• Puzzle state sharing
• Chat messages

The game gracefully falls back to solo mode when no server is available.
