There are couple of reason for why main story is being stalled;I mean if the numbered release versions are true to what the final endgame is then i wouldnt rule it out. As far as Im concerned the story doesnt seem to have an end anywhere in sight and we've had no more quests on finding out who the "real mom" is for what seems like forever.
But this is the most consistently updated game next to NLT's stuff.
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.
