One more LI will be making her appearance in the upcoming release, obviously with it being late game she'll be a bit different than the others, but we'll see how everybody feels when she comes out.I think any one of the girls could be a legitimate LI but as they say, they all have issues, as does the MC. Does not appear any more characters are going to appear in the story(?)
One of my big goals was to make sure that most of the girls wouldn't have a "hard lock" until near the end of the whole thing, that way if in say this next release you learn something that really makes you like insert girl here you aren't completely stuck because of a choice you made three chapters ago. As long as you spent at least some time with them most of the LI's will be available.And who knows, maybe we get a second chance with the girls later on, when we have learned more of all of them.
I want to make as many path's feel viable as I can within reason of course. And of course if nobody jumps out I want that to feel like an acceptable choice as well. Within the constraints of the story I want you to be able to do what you feel, that's part of the fun of VNs.
