From what I can tell, the reasonings for the rewrite was so the game can 1) flow a little better and 2) is so more content could be easily added. I think it was mentioned sometime back that a new programmer was hired since the code was a mess or something. I believe this was sometime April. This in theory means new updates should come in sooner and in more regular intervals. Also some of the content was removed to be added at a later date for when scene is more fitting towards the story.
I don't particularly mind the changes but this is coming from a guy that only recently has kept track of this game. I think some story parts are a little off character but I can't fully recall some of the events of the show. I feel like the choices you make may affect how the story plays out but it's too early to tell at this point, which I do find annoying that it isn't mentioned if this is the case or not. Overall, while I don't think this is a solid update, it is technically a good introductory to whats to come. I also understand that they needed time to really get a good foundation for making updates and making story flow but unless the creator has a good road map at this point, I can't be sure how well this game is going to get in the later months.
