Well, that's essentially what happened. The game was never meant to be a game but just a trial in which DC wanted to teach himself how to code. It became popular, he hired some people who continue to built on his stuff and after ~ 1,5 years he simply had to make a decision. To either make it properly, consistent and playable (including having a really playable supported andriod version) or to finish everything in a rushjob with partly really bad art, bad animation, no saves, no proper mobile version, etc. and most importantly no real prespective.
I don't think there are many people out there who really like that approach but I think it's price worth paying to have better game in the end.
Edit: Just to add, I don't think Mia's initial route will change much. After all she isn't like for example Jenny, where the original content was just really bad all around and had to be replaced.
