KISS files are somewhat interactive "games"
Most are rudimentary where you can click on clothes and drag them from a characters body.
Some incorporate some type of logic where you need to do things in order or click in an exact location.
More complex ones are animated , have complex logic structures, sound, detailed drawings
and show reactions to things you do.
One of these can be found here.

These may not be for everyone. I believe KISS was started with Anime characters in mind
so familiar traits of the genre are present in many KISS artists characters (Doe-eyed, youngish looking)
They also can get graphic sexually and rather strange at times.
You need a KISS viewer (there are a number of them do a google search or check this site) and download the different stories.
This particular artist incorporates many things in to them and the game will end if you dont do sequences correctly.
Can be frustrating.
The stories are free but charges for the "walkthroughs".
Disclaimer: I dont know the artist and I just found his/her site recently.
