Honestly just kinda wish dev went for the harem setup.
30s update unless you actually like an LI seems to be a rough way to garner support for a story ngl. Like me personally, I wouldn't pick jade because theres no appeal to me there, not a big fan of her model/character from what i've seen so far. Which to me just feels like it favors X supporters over Y supporters (aka every single char thats picked for an update will have some sort of negativity because X people want X's update Y's people wants Y's so on and so forth) and will end up causing dissent every update lol. Idk just food for thought anyway. Never been a big fan of single route games cause they usually dont change much from the norm aside from character specific scenes that werent there but everything else is pretty much consistent to the point that you're just holding skip to each char specific scene.
Dont get me wrong single route games are fine when its like one branching path, theres girl A which is section A of the storyline ie: "the good side" then theres girl B which is section B of the storyline which is "the bad side" so they're completely different from one another, Side A would be like traversing heaven, and everything relative to heaven, angels, etc. where side B would be like going down to hell, and dealing with demons, corruption, everything to do with hell kinda deal. But... instead its usually like the story is linear, but theres 4-6 branches that minorly influence the linear storyline and its everything you've seen before with just a slightly different spin.
