Yes, the game does take a very long time to develop. There was a good chunk of time where the game kept having lackluster updates one after the other, but I feel the last 2 updates have been pretty solid. Gumdrop seems to have found some footing, and direction. The way 0.98 ended on the sons side was pretty good, and it definitely left me wanting more. This coming update with the dance, and everything has a lot of potential.
I've come to learn that you can't approach this game like you would a game like Dreams of Desire, or Milfy City. I just wish development time wasn't such a huge grind.
