Most of the problems of this VN stems from the fact that the author is trying to deconstruct a medium and a genre he doesn't know much about.
You end up with a story where half of the time it's a generic and tropey 'dating sim' and the other time it's a showcase of predictable creepy moments with a few interesting parts here and there.
I don't believe this is as bad as people believe it is but it's not really a groundbreaking title by any means.
