Had some trouble downloading at first. (and it's large size) but finally got it.
Really well made, the atmosphere and feeling of the story really shined through. The disclaimer was a bit weird, being that the weapon's being used against the dead (otherwise the characters wouldn't be able to survive? -- unless you're sorta saying that they shouldn't have used it :P)
Depressing ending though. EDIT: I do want to point out that this is one of best entries to the gamejam IMO.
