Claude Opus 5.5 in particular has been hailed for its smarts and creativity from its release (especially compared to its relatively contained cost in comparison to the behemoth Fable, or the OpenAI rival Astra). There&rsquo;s tons of examples of images, videos, and even music made with Claude, and I&rsquo;m sure quite a lot of games too. I decided to experiment with it myself to test the limits of it, and what it could do. My challenge was to make a game <em>entirely</em> with Claude. No separate AI models for image or music generation and basically no manual coding - just me prompting my way to a full, functional browser game. The chance was offered to me by the <a href="https://itch.io/jam/littlejs-jam">LittleJS Jam 3</a>, a friendly competition for amateur gaming that is quite accepting of AI coding and asset creation [^1]. The competition&rsquo;s only requirements were that the game should run in the browser, that it should use the LittleJS game framework, and that it should adhere to the chosen theme keyword: <em><strong>zig-zag</strong></em>.</p>
