As for the number of spellings and grammar mistakes - the problem is, that in a book it's MUCH easier to proof read at the end, because you just go page by page... Here are at least some lines which I probably haven't read slowly after I read them. I work on the project mostly alone so I have to wait for players to point me some errors...
With boys in the kindergarten is simpler than it seems. With men at the beginning I wanted to get some speech effect, but later on with more complex dialogues I realizied it might be too difficult for the players to follow - especially in some quest pointers. I gave up on the manner just for the game purposes. Sorry if it hurt consistancy.
With men still attacking I would call it a coding mistake rather than story one... I don't remember how it was, but my guess is that I just forgot to adjust it in the right way.
Random girl dissapears after she mentions a dangerous area and if I remember correctly Meretrix even hopes that the girl won't go there... Random girl dissapears because she clearly went to the hunting area alone and was eaten...
As for the mother - well, it might not be so obvious... If you are going to shop and returning from it, do you enter a house which is on the way every time just because it's there? If Sorv was familiar with what's in the cave he could just skip it on the way.
I don't remember how fire triggers with 100%, but I am almost sure that it just requires women language, as Meretrix needs to be able to talk with Igna right after the girl wakes up.
As for the game breakers. Really sorry that these are in there...
As for the third part with Bonatievour there is a hidden way to get through it in the game, but no hints are there, but I believe it might be triggered somewhere in the Women Dormitory.
