Local AI Model Qwen3.5-35B-A3B Builds Fully Functional Flappy Bird Clone in Two Hours
In a striking demonstration of the evolving capabilities of locally hosted large language models, a developer has created a fully functional Flappy Bird clone using only the Qwen3.5-35B-A3B AI model—no external code libraries or human coding beyond initial prompts. The project, shared on Reddit’s r/LocalLLaMA community, underscores a paradigm shift in how developers interact with AI, suggesting that on-device models are now capable of handling intricate, multi-layered frontend development tasks with surprising fidelity.
The user, known online as /u/Medium_Chemist_4032, began the experiment by simply requesting a Flappy Bird clone built with HTML, CSS, and TypeScript, initialized with Vite. Within minutes, the AI generated a working prototype. Impressed by the initial output, the user progressively layered on advanced features, each time refining their prompts. The result? A polished, interactive game complete with procedurally generated sound effects, parallax-scrolling mountain backgrounds, a flock of animated birds drifting across the sky, and a fully functional audio settings panel—all without a single external audio file or pre-written library.
Procedural Audio: No Files, Just Algorithms
One of the most technically impressive aspects of the project is its use of the Web Audio API to generate all sound effects programmatically. Instead of embedding WAV or MP3 files, the AI created dynamic sound generators for flap noises, collision impacts, and background music using oscillators, envelopes, and noise filters. This approach not only reduces load times and file size but also demonstrates the model’s grasp of low-level web APIs—an area where many AI assistants still struggle with precision.
Parallax Mountains and Animated Flocks: Overcoming Visual Glitches
Initial attempts to render scrollable background mountains resulted in visual artifacts and misaligned layers. But after a few iterations of feedback—such as specifying "use different opacity levels for distance" and "maintain consistent speed ratios"—the AI corrected the parallax effect to create a convincing sense of depth. Similarly, the request for a "flock of birds flying from right to left, smeared top to bottom" initially produced erratic motion. Through iterative guidance, the model learned to simulate flocking behavior using particle systems with randomized vertical offsets and alpha blending, producing a natural, flowing effect that mimics real bird movement.
A One-Shot Settings Panel
Perhaps the most telling moment came when the user requested a sound and music settings panel. The AI generated a complete, interactive UI with sliders, toggle switches, and real-time audio feedback—all in a single prompt. The panel adjusts volume levels for background music, flap sounds, and collision effects, and persists user preferences via localStorage. This level of integration, typically requiring hours of manual frontend development, was achieved autonomously by the model.
Implications for the Future of Development
This experiment challenges the long-held assumption that AI-generated code is merely a starting point for human refinement. Here, the AI didn’t just scaffold code—it iterated, debugged, and optimized under user guidance, functioning more like a junior developer than a code autocomplete tool. The success of Qwen3.5-35B-A3B on this task, running entirely offline on a consumer-grade machine, signals that locally hosted models are maturing rapidly. For indie developers, educators, and hobbyists, this could mean faster prototyping, lower infrastructure costs, and greater privacy.
As AI models continue to evolve, the line between human and machine coding may blur further. What was once considered science fiction—building a complex game from a vague description—is now a two-hour afternoon project. The future of software development may not be about writing more code, but about asking better questions.
