Kisekae Set System V2aka KiSS Dolls
Kisekae set system, Kisekae for short, is an early internet form of dollmaker, the explanation is a bit more complex than that so head over to the wikipedia article if you want to know more. They used to be made in their own script language and required a custom program to be played.
What you will find here is a spiritual successor to that, or at least I like to think so. The idea was to keep the format and style of early kissDolls but using modern technologies that are also easy to access and play without having to download a bunch of stuff and fighting compatibility.
