VERY GOOD. I already like this type of games where you solve everything with the phone, like Mystic Messenger or A Normal Lost Phone etc. and Simulacra made it with horror, my favorite genre. Using real people is something I don't see much in games, it doesn't necessarily mean it makes anything better or worse, but I think it went well with Simulacra and added a lot to the creepiness. The story itself can be a little lacking but compared to the fun and thrill I felt while playing this, I don't think it's a big deal.
