I think I get the plot
A man standing in front of his love's grave goes off to find her soul and bring her back. After facing countless monsters and the king of the underworld itself, he finally finds her soul but is unable to look at her lest she vanishes for good (hence the title) He returns to the grave only to see himself still standing there and realizes that it is just a fantasy. Unable to move on, he continue's his fantasy. Repeating over and over, he is unable to let go of the past (which I believe is the true theme of the game and where the title really comes into play: Don't look back at the past, move on and make new memories)
am I right? I really want to know.
Really good game even with the crappy graphics. (tho I tend to rate a game more on plot and gameplay as well as soundtrack which is why I give this a 10 out of 10.)
