I loved everything about this... except for the gameplay.
The design was cool, the art was cool, the humour was great, the voice was great, the fangs were awesome, the concept and theme were excellent... there just wasn't much game to it except for random guessing. My best score was one. At first I thought it was kind of a joke game, and you would always be wrong. But then I got one right. Then I thought there would be hints eventually, and then it turned out to just be guessing.
I think adding some way to figure it out, clues, hints, or at least a way to rule out one of the choices. Maybe a certain number of "monty hall" options, or something would go a long way to making it more fun to play more than a couple of times.
But still, you should be happy. The game felt and looked awesome.
