At Cursor Vibe Jam 2026, an iOS developer with nine years of experience showed how it’s possible to rely entirely on AI as he showcases a Capybara food delivery game that he successfully made in only two weeks. Using Claude Code, the developer reveals that all lines of code were written entirely by AI, while also providing a detailed guide on how everything came to life in this virtual world that consists of both single-player and multiplayer elements.
Using $100 to upgrade from the Claude Code Opus 4.7’s 5x plan to the 20x one, the developer used a combination of services and programs to complete the game
A lengthy explanation of the Capybara game was provided by talented Redditor “Ieocoout,” who claims that 100 percent of the code that includes more than 188 commits and 27,000 lines of programming, logo, illustrations, textures, 3D models, and more, was made entirely by AI. For the developer’s input, he says that prompts for the code, artwork, audio, and 3D were provided by him, not to mention fixing development gaps and fine-tuning the game that AI initially couldn’t tackle. He also included a small gameplay clip at the bottom.
“The game was entirely vibe-coded. In practice, I spent most of my time brainstorming, planning, and playing rather than generating code. I ran 2–3 Claude Code sessions at once, each working on a different part of the code to avoid conflicts. New features always used a fresh session with no context; I kept one long-running session for bugs that needed more context of what was already built.”
While it might appear that vibe-coding is a cakewalk, it’s anything but. Using AI to generate a 3D map was difficult, so an editor had to be used to build one manually. An European-style city was the developer’s theme, and after several hours of work, he had a “genuinely playable city” on display. As for the multiplayer aspect, one would assume that this would be a Herculean task, but Ieocoout says that it was quite the opposite.
“Multiplayer was simpler than expected for a jam. A single global city/lobby hosts the room over a live WebSocket on Cloudflare. As players join, their position and item stack are relayed to everyone else.”
All the other bits and details came later to enhance the environment while also uplifting the user experience. In short, vibe-coding delivered one heck of a result, despite the fact that it was a two-week effort, but it shows the possibilities of what can be achieved with AI. Then again, we doubt it’s possible to achieve similar results for a layman, but using Claude Code is certainly a productivity booster for those possessing similar skills and forte.
We recommend checking out the entire post on Reddit so that you get the complete picture of the game. After all, such an effort deserves some applause.
