Description

An unsettling reimplementation of Flappy Bird featuring a dark aesthetic and a built-in tester bot. The AI model autonomously decided to implement the testing bot to verify game functionality by taking screenshots and evaluating game states frame-by-frame during execution.

Details

Why this is interesting: It demonstrates advanced agentic behavior where the model autonomously built a self-testing harness to verify its code.
