Just here to point out that at 12:30 into the film, apparently EVERYONE slept in the woods the previous night, because it cuts to everyone waking up in camp alive and going about their day.
Killer throwback style slasher in the vein of Hatchet, Sleepaway Camp, etc...
Enjoy it for what it is; a gory slasherfest with awesome practical effects that stays true to the genre.
