Very atmospheric and unsettling. Well done pixel art and a soundscape that perfectly matches that setting.
It's a bit slow at first (especially collecting water) but becomes pretty manageable once you get the fox mask. Collecting wood and meat even gets easy if you let the fireballs do the work...although that gets more difficult later on. Especially if you run into two devils at the same time, like I did on one occasion.
Completing the game took me well over an hour, as I just couldn't find the last health upgrade. The instructions were pretty well explained, though. My only criticism here would be the note that explains how you get meat. The rifle is pretty obvious and the meat could also be figured out, but the thing in the middle is a bit cryptic. Maybe a deer head or something similar would be more clear. But players will probably figure it out anyway.
Still, a great little horror game!
