I definitely like the idea of a western zombie setting! I like western settings in general, though.

As you said, the game is not complete. So I feel I can review it without having played with another person and simply playing through in my own.

The core of the game is solid, people love talking about survival especially in zombie scenarios. The idea that someone can have a different answer and present a good reason ... that is very compelling and very worthy of building upon.

Obviously you'll want to finish adding answers to the multiple choice questions :P

I think most of the questions meanings do not get lost in translation, so good job there. But there is one question that I really think is far too open ended and it's the "Are you human" question.

Overall solid idea and setting, I definitely wish to see a more playable version!
