I have managed to expose some native apis from iOS, web, Windows and Steam but that is far less straightforward and the LLM is sure it knows what to do and it does NOT. Web searches are not great either.
I made https://love-15.com which works on the web and as of today is on the iOS app store. I'll probably get it on Steam after that. I prefer playing the native builds personally.
It's fully free and about the smallest game design I could think of - I did it partly from a longstanding desire to make this specific game (I played a very similar thing decades ago on Palm Pilot) and partly as an experiment about just how much work can you get an LLM to do.
