Just wait, I prefer them taking their time to give me free updates of a game I don't need to pay to play, rather than keep making them work for free and give me updates as if they need to release builds every X months or so. In the end, if they do it out of their own free time with care, we will have something cool and fun and very well done. I prefer that, rather than having this game repeating the same things the original did and never reading through the rest of the routes :D
The closer they get to the finish line, the harder it is to release faster though.
