I wish the author had a better understanding of slow-burn horror, similar to Shiki. As it is, the village is so obviously wrong that by the end of chapter one it's obvious to the main character that the village is full of cannibals. We as the reader are the only one who should know that until they're ready to make it an issue. You cannot hand us DIRECT evidence of cannibalism and then have the MC shrug it off when he obviously knows whats up. A human bite mark on a corpse is a BIG FUCKING CLUE, which is stupid. It also doesn't make sense, why would you sink your teeth into something without eating any of the stuff?
If, instead of human teeth marks, it had been a small human-mouth-sized path of flesh missing from the corpse, then the MC would have had slowly building paranoia instead of NO SHIT SYNDROME. Like "Oh maybe the body was attacked by other animals" and "there's no GUARANTEE someone was munching on the corpse, thats just the delusions of the gambling addict who was here last". At this point, the village is more suspicious than the town from Hot fuzz, and that was a COMEDY.
Without that bit, this would easily be a 9. As is, 7, and I hope it gets better. Not very many people dabble in the cannibal genre these days, and it's always fun to see.
