Thank you so much for a kind feedback!
Progress depending on 100% of dialogue is intentional, to make the gameplay time a little bit longer. It wouldn't have much effect if a player got murked almost right away after ordering something, it would be too fast and rushed, in my opinion. So dialogue is there to make the player a little bit more comforted before they go into horror section. As a gamer, I can understand why it's frustrating to sit through dialogue sometimes, but as a game developer, I'm here to make people suffer (That was a joke!). And no, the game won't be expanded, it's done!
As for the endings, that's why I included a walkthrough actually!
