This was a pretty good read! I personally think that the narrator should've had more of a personality; he seems like his only purpose is to tell the story, and it would be interesting to know more about him. But that's really the story's only big flaw in my opinion (aside from occasional grammar issues, but those are typical of pretty much all writers); everything else was good! The pacing was good, the story was absorbing and mysterious, and the twist at the end was really cool! Overall, a very engaging read; again, it could have had a little more personality, but the eeriness and mystery surrounding the story definitely make up for that! Nice work!

Deliciously creepy!  I really like the story here, and the way you write makes it easy and enjoyable to read.  Some of the action (like the prisoner punching the guard in the jaw) felt a little slow, but the story itself was just the right pace.  The ending is great :)
