I don't know whether to put this in the reviews or comments...maybe both?
I have one small complaint: there seems to be no reasoning behind the right choices. It's like whether you live or die is mostly based on luck. For example, the very first choice you make in the story is between a knife and a frying pan. If you wanted to kill the zombie, the obvious choice would be the knife. If you wanted to create space between you and the zombie, you'd use the pan. Either could work in terms of keeping you alive. My suggestion is that you add some small clues (ie. the knife is farther away) and make it so that the right answer is based on logic and reasoning.
But other than that I think you're a great writer! Keep up the good work! :)
