I created a new world: https://infiniteworlds.app/shared/qTLMXY

It's not as sophisticated as many of the worlds posted here, but it should be considerably cheaper. The story is that you wash up on Amazonian shores, but all of the Amazons are small (but proportional).

For my own play through, I told them what fetishes I had (including age regression), which allowed for the girls to be de-aged to whatever age I wanted and still be fuckable. I also included snuff. It defaulted to non-permanent snuff, but you could probably specify otherwise and I think they would also comply.

I did open the debug mode in order to make it so that the goddesses of the land had already told their people what to expect, and that they all were eager to fulfill those desires, but it might be possible to get immediately to that point without doing that
