I think you have to understand the developers, they make every effort to get the update as soon as possible.
Milfy City has a very complex history and pretty good images. I only make a comparison with DarkCookie that in his game Summertime Saga earns 50K per month and performs between 1 or 2 updates per year. I remember that when ICSTOR started between version V1.0 and V4.0 it did so in just one year, and now that it is taking a while, everyone goes crazy.
MILFY CITY is a very good game and with a lot of effort, I prefer to be late but done, to take it out quickly and be boring and with holes in the plot.
