For your Where the Heart is Walkthrough in Episode 2 when rubbing sunscreen on Katie you have the choice "Do them yourself" listed as continuing the scene but it stops the scene early. It's "No problem" that continues the scene with additional choices.
Also in Episode 7 just after you meet Bella and you ask Katie "Compared to you?" the "(Joke / Insult.)" option has the text Katie +=1 after it and I think that should be a heart instead of the text.
Looking at the scores at the end of each act the values seem to add up but I am only up to just before Episode 8. If I find more I will post.
