Frustration? No way. I knew from the start that alternative route will not be as warmly recieved as the original one. At that moment, I was in mood for more emotionless corruption, so I wrote just that, everything else was just a background. The mood didn't last until Yuria's corruption, so she got a different makeover, it's as simple as that. :>
Again, I am writing mainly for my own tastes - even if they do not always align with the "market demand".
Also, I have a general outline for third game in the series ready (wherever it'll come to exist depends on many factors, so do not treat it as an announcement :>), and it's vastly, vastly different from previous entires - no doubt leaving some folks who enjoyed Isis/Valdana very disappointed. But I don't wanna write the same basic story over and over again.
