I love the survival theme, and am a sucker for end of the world stories, but this seems like an introduction.
There was no story about how the monsters came, how rampant the infestation was or wasn't, or anything. No meat to it, really. No plot.
I want to know how the character survives afterwards. Even before.
As far as introductions go, this is good, but needs to be fully fleshed out to be considered great. Keep at it, I would love to see a meatier product!
