I've been following this game for some time. And this game used to be a lot smaller. It was more a straight path that with a few different events based on choices, that you could see everything in about an 1hr.It is only recently where it started to become more full as far side story. With the different paths on characters, and different interactions.
And as far as your first possible solution, working as a team, is why Milfy City no longer gets updates. Icstor is a team, but according to Icstor himself he is dragging his feet, while the rest of the team has already done their parts. Which, lets go for a moment just for the sake of argument and say Westane is dragging his feet, how is hiring a team going to be any different, when each team member contribute, but Westane still drags his feet? Also if you hire a team, unless you say its my way or the highway then it get creative differences, which may improve the game, or even make the game "worse", in theory.
I remember seeing a road map for this game where it was the John content and then it was going to home content and then something else and so far, it appears that Westane seems to be sticking to it.
Note: I say this all as sake of argument or in theory, as my personal opinion on the updates, is I see no problem with its current course. Sure my views can change, but I'm not so quick to abandoned or throw in a towel because of one or two set backs, when there's not a history of screwing over peeps.
