The graphics are good. I don't like the invisible walls or the lack of new spooky music when the candle is out. Enemies just spawn even if you have a candle full. They are big, but they don't have presence. Good game though.
All they really need is a more spookier way to showcase they are threats. This would mostly be done with the sound effects. Like a scary distorted howl randomly before seeing them and/or more powerful effects on the eyes that is blinding the MC into darkness.
