Hosted model: Qwen/Qwen2.5-Coder-32B-Instruct

Users describe a tiny game in natural language. A small agent chooses one of four safe render tools:

—dodge
—collector
—jumper
—snake

For strange mode, the agent can blend two render tags into one playable game. The AI designs the cartridge: title, theme, goal, difficulty, controls, hazards, collectibles, and twist. The renderer owns the game loop, collisions, controls, and Gradio iframe safety.
