I think the developer has focused too much on what he likes and not what subs/followers like. There was content the original game structure was fine as is, but he decided to overhaul it to improve mechanics, etc, which is a daunting task for any developer to do to their game. With that said, there has been no time to introduce new characters. On his blog site, he listed new characters to be introduced later on in the game, but later on has yet to come.
