A lot of game elements make no sense in that regard. Like why do we need the breeding facility in the love route. (Even in slave route I find it annoying, where is the fun in impregnating faceless women? Put May, Ty Lee and Azula in there, now that would be a slave route worth it's name.) Who is the blonde girl in the dungeon and why can't I really help her, why should I care about her? Also lots of the h-scenes are too similar for the different states. If the pacing would be better, you could get much more satisfaction out of breaking Azula.
There are tons of minor issues like that but I don't really want to complain. For me it's still the best trainer game out there. If we're lucky and the demand is there Mity might consider to do a final improved version when book 4 is finished.
