I suggested the ice cream idea to Cookie last year and he thought it might be a fun idea. I dunno if he remembers it now though.Well, the game is free so you can't really pirate it.
I'd actually argue that not much has changed. The overall content was basically worth the 3 month the last update would have taken if it wouldn't have been for patreon (4 complete story lines is a lot). I think the progress seems a bit slower because the sex scenes etc. became a lot more detailed and include more frames which takes quite a bit of time and because there are more details in general. At least to me the amount of content per month hasn't really changed, the only difference is that the updates are way bigger than they where before and include a lot more quests/ non h content and story. To me it seems like DC wants to move away from those "get money and buy item x" quests which is nice but all those alternatives/interactions take quite a bit of time. Of course, if you want to focus on pure sex content, it's likely not perfect but I guess that's to a degree what makes the game special.
I'm pretty sure that's a given at some point. I wouldn't expect that in Diane's next update (maybe, if we are lucky... who knows...) but some time later. I think Judith is a very strong contender for a later update and I'd personally hope for mum and maybe Jenny as well.
I'm not sure about that though.
