Just realized I forgot to rate this so came back to do so. Music was great. Gameplay was kinda tough for anyone that read Old Yeller, which is why it was great, too. You added a level of emotion/attachment. And.... you created an alternate "Cujo" ending for Old Yeller.
Anyways, you gotta shoot anything that acts unnatural, and don't fool around about it. It's too late after they've already bitten or scratched you.
