itch.io

I personally use grok because it is the most nsfw friendly and is happy to generate feedism stuff.

I tried it out with a few others and they work to varying degrees but most stop once it gets too obviously fetishistic

The game started life as instructions for a chatbot that you uploaded but it kept not playing nice, so I separated the calculations into a separate calculator. Over time, more and more of the features got built into the calculator until pretty much everything was in the calculator and I ended up with the game.

I understand that not everyone would enjoy this sort of approach; you're under no obligation to play it.
