There are couple of reason for why main story is being stalled;
1. KsT is still trying to get to last pledge goal
2. Supporters are heavily influencing stuff in game; as far as i know no one seems to care about the story(pledger wise) which i agree cause game is fun with all little bit of quests around sandboxish style.
3. It is hard to please everybody, so KsT is contantly improving variety of fetishes in game to keep people happy
4. I wouldnt consider opnions of f95 users here, try reading KsT pledge page more. I mean given %70 of f95 wont pledge and just underage kids.
