Ludum Dare 59 just wrapped up last week, and both first and second place were won by developers using "Agentic" coding tools, something the community there is still discussing:
For what it's worth, the non-AI-coded entries were still quite good relative to the winners, so it's not so obvious that AI use confers an unbeatable advantage.
I did vibe code jam 59 entry with friends, the spirit of the rules there's a lot more lax. We didn't even get to top 100, but that's mostly due to gamedesign errors, not tech. This is the first entry in years which was vibecoded 100%, and I have very mixed feelings about it. It's no doubt anymore - 1.5x-2x speedup, which makes not using it (if allowed) a complete no-go. But psychologically it's tough losing control, and changing workflow to managerial one substantially, it diminishes the craft.
