Sadly, my own small game-dev adventures look similar: I can implement the core mechanics fairly quickly, but polishing the game takes ages.

UPDATE: without AI usage at all (just to clarify).

We use both Claude and Codex on a fairly large ~10-years old Java project (~1900 Java files, 180K lines of code). Both tools are able to implement changes across several files, refactor the code, add unit tests for the modified areas.

Sometime the result is not great, sometimes it requires manual updates, sometimes it just goes into a wrong direction and we just discard the proposal. The good thing is you can initiate such a large change, go get a coffee, and when you're back you can take a look at the changes.

Anyway, overall those tools are pretty useful already.

This is great! I'm not really into electro, but I really like this one!

Maybe I'm nitpicking a bit but the second concrete example shows different flow in the parent method compared to the first one. If the second example would be a modification of the first one like shown below the output would be the same in both cases.

  async def parent():
      print("parent before")
      task = asyncio.create_task(child())   # <-- spawn a task
      await task
      print("parent after")

...and dependencies between teams/stakeholders. :)

Works super smoothly on my Pixel 5 4G.

Excellent work in general!
