Where is the line of "no AI" exactly?
While the game certainly isn't vibecoded, I would bet some Pocketpair devs used an LLM for a Python script, to figure out something in documentation, to point them somewhere over an error, maybe some Windows issue; you know, utilitarian things.
Artists likely use oldschool ML models in their graphics software, without even knowing it. Or maybe when processing textures to finish them. Or to search through assets, or documentation.
I'm just saying, if you're strict with the definition, it would be really hard to block an entire dev studio from all "AI." It would almost certainly seep in from casual use, legacy integration, or "oldschool" things like image recognition and processing.
It doesn't mean they have to vibecode or ship slop assets, of course. When they say "no AI," that's what I hear, and exactly what I want.
But I think studios, especially larger ones, need to be careful about labels like "100% human," lest something come to light that seems to contradict the guarantee.
