The atmosphere and art style are pretty cool, but I have an issue with the Devil. I'm not sure if you were specifically going for making him scary but I just found him annoying more than anything else. Like it just felt as if my survival when he attacked was pretty much luck based. I didn't find a consistent way to avoid damage, which may have been the point, but it just meant that if I was too far from a salt circle I was going to die not really due to any fault of my own.
Unless, of course, there was a way to know when roughly he was going to attack that I just missed entirely. If that were the case I guess you could go "alright I have about this much time, so that should be long enough to reach this salt circle" which means it would have been my fault if I was caught with my pants around my ankles. I also would have had him show up less frequently but be more dangerous when he did.
Oh, and to anyone who finished this game on "Unforgiving" i salute you!
Edit: Oh, the wind chimes. Wow, I'm an idiot, never mind.
