It is a short story with the background of a typical zombie apocalypse. So nothing new at all, but how is it executed?
Principally not bad, the paragraphs are quite short, so it is an easy and fast-paced reading from choice to choice. And there are some choices and some endings, so yes, this is interactive. On the negative side it is a short piece and the ending is a bit too abrupt -- an open ending. I felf slightly unsatisfied and did not have the feeling that the story had come to an end... it did not seem like a resolution to me.
Nevermind, even though I think this can not compete with the flagships of interactive fiction, it is surely worth a try.
