Use case overview

A content creator with no coding experience used Claude Code to build a black-and-white wave-combat platformer in HTML canvas and played it live.

Reported experience

  1. What they did

    A content creator with no coding experience used Claude Code (Opus 4) to generate a game called 'Seek' in HTML/JavaScript canvas. It has a silhouette hero with an oversized sword, wave-based combat, four enemy types (grunts, archers, brutes, flyers), and an ending tied to player choices. The creator then played the result live.

  2. How it went

    The game closely matched the creator's original vision. They reached wave 10, where they met a boss that seemed unbeatable. They endorsed Claude Code and teased a future comparison with Codex.

  3. Worth knowing

    The daily.dev page only summarizes a 12-minute YouTube video, so the exact prompts and any fixes aren't described. Watch the original for those.

Example prompts

Try with Claude Code
I have no coding experience. Build me a 2D platformer in a single HTML file with a [art style, e.g. black-and-white] look and [core mechanic, e.g. waves of enemies to fight]. Use simple controls like [keys], explain how to open it in my browser, and keep improving it based on my feedback. You're finished when I can play a full level from start to finish.
