I would say somewhere in the middle. A good chunk of content every month or 2 would be nice. I hate when devs release small updates that lasts like 5 minutes. Waiting 6 months or longer for an update is too long in my opinion.
I would prefer a game be abandoned. Rushing the ending would ruin any attachment to the story and characters, that the dev created in the first place. At least with an abandoned game, the dev can always come back and continue working on it.
I agree with the mom and daughter being too thick, but I still think they look good. Hopefully we can get some slimmer girls in the future, if anymore are introduced.
