I do like the idea, but I have a few things to say.
Not the best writing in the world. Weird, awkward to describe creatures. Awkwardly arranged, somewhat cliche dialogue (really, there should be more than just a sentence or two of dialogue). Also, how does he manage to push the door open after you push your couch in front of it.
Still, it's a refreshing concept. I think it will be a whole lot better when it's finished. Good job so far.
