It's too creepy for me. The game is long, dark, full of suicide (or lifeless bodies) images, psychedelic visuals and probably has some supernatural stuff. I don't say it's bad, it's just not for those who are afraid of playing real horror games.
Playing 'missed memories', I couldn't get why the visual novel is marked as a horror game. Now it makes much more sense with the dark atmosphere and all these old photo/film effects.
