it is an unfinished, still in development game from an indie developer. If you wanna learn which action does what or what flag unlocks what scene you should use the walkthrough. Current state of the game is half-sandboxish at best. And since content in this game is created and added bit by bit you gonna have to endure following certain paths and lacking freedom of open world games.So, what you're saying is that the only way to guarantee that the player doesn't encounter any bugs is if he doesn't really play the game, but instead follow a walkthrough? And wanting to complete the game without said walkthrough isn't something someone with common sense would ever consider?
I mean if you are patient enough you can come back in a year or two and see how it goes. Dont expect much logic behind gameplay either. I mean most of the stuff you do in game is to keep you busy. Effort and reward kind of relationship which btw tries to extend your play time so when you fully complete it you will have something to look forward to(other than stroking your dick ofc.)
Btw; this is my take on how KsT rolls.
edit: also this is a sex game dude. Not some mystery plot or adventure game like Baldur's Gate. To be honest main plot has been put on hold for a long time and it is quite cliche. walkthrough is merely there to show you how to reach which scene. And it is getting messier by each update cause there are too many variables tangled up.
