Well... First time playing this I got plenty terrified. Didn't like the game so I quit. Now I came back for the medals and the game didn't scare me as it used to. I was most afraid of losing so I had to start over. Figured the strategy was to switch direction you aim the light at as often you can. The walkthrough was otherwise helpful.
I am not a fan of scary horror games with sudden jumpscares and the likes so this game did not appeal to me as very exciting. The graphics could have been better, but they were not the worst. I do like that nothing was completely luck based. You could prevent the demon from getting you by looking at it and if it gets you you get a chance to escape by bashing some keys.

"The woman gave birth days later, it was a boy, healthy, normal... Apparently normal... Except for..."
...he was a demon?
That could be the reason for why the mother was trapped. Maybe the demon just wanted its demon son. Although it did tell you to kill the baby once, but maybe that is also part of the ritual to release the demon in the child. You are basically the intruder who breaks in and kidnaps its baby. No wonder why it is mad at you.
