I don't think it's that scary. I mean, it's certainly creepy and dark at some points but nothing too hardcore.
I personally liked it, I loved the atmosphere and characters, it's one of my favorite series of all time
I have lots of VNs I'm looking forward to. I'm pretty hyped for Grisaia no Meikyuu, since i absolutely loved the first game. Other stuff includes Little Busters Ecstasy, Rewrite Harvest Festa, and Angel Beats. though i doubt they'll get translated anytime soon..
