I am absolutely gobsmacked how good the game is! I didn't complete the level fully but I completed all but one of the tasks. This is both smooth and fun and I'm surprised that a modern LLM can do something this well, let alone in a single file. It makes me realize how much the goalposts have been moved. A few years ago (ChatGPT 2? 2.5?) wasn't even able to implement a small Python script I would expect a junior engineer to be capable of producing. Now we're getting the tools to do something like this. You should think about how to "rate" the outputs or at least provide your own rankings.
