My page dedciated to the kisekae set system, also known as KiSS. It's an interesting piece of software mainly used for dress up games, but is capable of more than that! I'm still learning how to create my own games but will share my projects here as I progress ^.^
I recommend you start with the KiSS viewer downloads page at Otaku World. Then, head to their Doll Library to download some KiSS dolls in the form of .lzh files. Some dolls come with multiple sets of wardrobes, which can be toggled layer by layer in the UI. Some are simple drag-and-drop doll makers, and others will have more interactive elements.
Head to the Otaku World Tutorials page to find more in depth tutorials.
