so BASICALLY it's a choose your own adventure renpy game, i love that we need more of those types of games allot of games i see just don't have that many choices or all converge on the same plotline, not allt that let u follow multiple different plotlines like this so i'm glad i found this.
i will agree with others that have said the huge boons thing is kind of a turn off (it's imo kind of a becoming more of a niche fetish these days) but that's not going to stop me from playing the game, if i had to suggest i would say don't make someone with smaller breasts magically get huge ones once transformed unless that was a deep desire of the character (in mia's case i can't see that being a huge concern of hers even in her deepest desires from the way u have written her) i could see one of the other girls that have very small breasts or a flat chest wanting huge ones deep down but someone like mia not so much.
question though are all the girls going to have huge breasts like that once transformed? cause if so that might just make me not want to play future builds since big breasts are a huge turn off to me, i prefer small ones (side note i agree with
pejman loli vampires are a thing (and in my case a huge turn on, not saying u have to have them though)) or average sized ones and i'm kind of sick of seeing the majority of these kinds of games cater to the big breast crowd (there are too few games that don't have huge breasted women and i think that is a disservice to those of us that don't like that kind of thing)
