I agree with most of the thing you said. What annoys me is...Well, I don't mind waiting - I'm not a pledger. But, If I try to put on the Top Tier shoes ($20 or higher), I'd be kinda frustrated with the short updates. Indeed, the last 5 or 6 updates were really short. I'm a defender of " value for money ". We must wait? No worries, but you've got to deliver. Never thought I'd say this, but I also kinda give up on Linda's story progression. The reason why is simple : when you build so much hype for nearly two years, you've got to blow everyone's mind...And unfortunately, I don't think it will be the case.
I like the Art and stuff, but if there's something slowing em down in anyway, they should get rid of that thing and try another to speed up things and create more content. I'd even refrain from complaining if milftoon drama said " Well, next updates will take two months to deliver, but it will be longer ! " . Anyway, just my humble opinion.
