After I completed episode 1, I was given a tally of my main choices during the game:
Of course there was more to it than these choices; the game nagged me about things like "He now knows your name", "You saved Clem", "Clem saw you pick your nose." Some of the choices even affected the "trailer" for episode 2.
Now that cool and all, but I'd still like to reach the ending of the game in one single go and not find myself screwed out of options before the end. I suppose there's worse endings and better endings, but that's what Youtube is for.
Do I need to worry about getting in unwinnable states?
