One Saturday, One AI-Powered Pirate Ship Battle Game, Built in ~7 Hours

Source: Dev.to

Introduction

How did you spend your Saturday?
Following up on those weekend vibe‑coding sessions where AI turns prototyping into actual fun (indie game MVPs at warp speed)… I randomly thought about a super simple ship battle game: tiny pirate ships, one cannon each. Nothing AAA, just basic fun.

Challenge: How fast can I get this playable?

I started at 1:21 PM with a Lovable prompt and, by 8:45 PM, was texting my wife “Done + ”.
Total ≈ 7 hours, including a 2‑hour shopping trip and dinner break.

Frontend & Basics (~2 hours)

• Used Lovable because credits were available; the choice of model (Claude, etc.) isn’t critical as long as it gets the job done fast.
• In ~2 hours I built:
  • Proper ship maneuvers and shooting
  • Game menu and health bars
  • All browser‑based, synced to GitHub

Backend & Multiplayer Magic (the painful but rewarding part)

• Pulled the repo locally and opened it in Cursor.
• Asked the AI to plan an authoritative server with matchmaking queues, bot fills, WebSocket (WS) communication, and a Rust implementation (needed for a tiny $6 DigitalOcean droplet: low resources, fast, safe).
• Encountered several issues:
  • Stuttery movements and flickering environment
  • WS connectivity flakes
  • Inconsistent message contracts
  • FIFO queue ordering headaches

I intervened a few times, knowing where these problems usually surface (frontend fighting backend state updates → constant re‑renders). The solution was to make the backend the single source of truth and let the frontend only render/interpolate, resulting in a much smoother experience.

Deployment (reusing my template)

Techy spoiler – skip if you don’t care.

• Infrastructure: $6 DigitalOcean droplet + free Cloudflare Pages (classic combo).

• Frontend pipeline: test → lint → build → Cloudflare deploy.

• Backend (Rust) pipeline:

  cargo test && cargo clippy && cargo audit && cargo fmt
  cargo build --release
  rsync target/release/your_binary user@droplet:/path/
  sudo systemctl restart your_service
  # nginx config tweaks, pull fresh certs for API, healthcheck

• One command, live.

End Result

• 9‑player browser lobby
• 60 fps gameplay
• Ships sailing, cannons booming, health dropping
• Synchronization across clients without major drama

All accomplished in a single Saturday. The prototype is desktop‑only and may contain bugs, but it demonstrates how weekend experiments become faster and more rewarding with AI tools.

Conclusion

Prototyping used to drag; now it’s pure fun, and you actually finish things. What about you? Built anything silly‑fun with AI on a weekend lately? How quick are your MVPs getting these days? Drop your stories below. 🏴‍☠️
