First off, I LOVE the game! It's unique.
Now, I like how you get to choose who lives and who dies, and I like that, but is that going to be the only choices you get to make? I know it's hard for a user to choose which place they are going to go to next, but it would be nice if they got to choose who they travel with. Say, if you got along with one character, and not another, you could choose to ride with them to the next destination, and on the way, the conversation you have will change the story.
Also, at the end of the episode, it shows how your decisions compared to other players. It would be cool if those decisions and percentages determined the location of the next episode.
Just some thoughts.
