Yup, the fetish is called "macrophilia" and (usually) involves men who get a thrill from being in the presence of a giant woman. I'm kinda surprised you found this game since it's supposed to pop up when you type the keyword "giantess" (female giant). And yes, it's 'odd' lol but not more odd than feet fetish and other things that are at least materially possible. This is a less known one since it's not something one can satisfy other than with art and games. I guess for those without the kink, the game could mostly be about 'horror' as being shrunk and having to survive an encounter with anyone would in itself be something scary indeed.
