I totally agree that it tries to fulfill a lot of fetishes at once and it's a great idea. Problem with this is that if there is not a lot of content (like, a lot) it will take much longer to actually be good. Because a foot fetish fan will be disappointed with a game with 2-3 scenes, same with each fetish. When (if) it gets bigger and there's like 10 scenes minimum for each fetish, it'll start being fun cause the core mechanic of being able to choose the current girl is very fun and you can just chase your fetish.
Therefore it'll only have the same success as a game that's more niche if the content volume is significantly bigger. Basically like one game for each fetish in terms of content, all put together with a nice storyline, fun gameplay and the core mechanic of being able to choose.
But since updates come slow and the game is still in very early development, I also think that finishing ANLIS first is a way better choice. Afterall a lot of people playing this come from ANLIS and for its top tier foot fetish content, so this obviously can disappoint a majority of them. Finishing that game first would mean building a strong community and support, both through messages and financially. You know how they say, find a nice, don't do everything at once. At least when you don't have the resources to do everything fast.
edit: ...but if Zenkuro's fart fetish has awakened and this is the direction for any new content across any of his games, then we're doomed
