I can definitely appreciate a metaphysical mystery. The atmosphere and the artwork are quite nicely done, and the battles with the coding errors were interesting. What I'm both intrigued, and a little confused, about is how each time the protagonist goes home, he seems to end up in a strange dream-like sequence, in a world that doesn't make any logical sense. Is the entire sequence of events the protagonist reliving past memories? Does the entire game take place in the in-between? Many questions. Perhaps the ambiguity of the situations is your intention, and perhaps it would make more sense if I had knowledge of the folklore this story draws from.
In any case, it kept me playing through to the end without a moment's hesitation, so good job!
