Please Answer Carefully is an interesting horror game that isn't done in the same way as most horror games. The type of horror it is is actually very interesting, but the medium really takes away some of the charm. Since you have to download the game and install it, you already know that it's just that, a game. However, if you left this "survey" up on someones screen without them having any knowledge about it whatsoever, then this would truly be a terrifying experience for that person.
This game is very well made and is very interesting, and the only real issue I had with it was the loss of some of the effectiveness of the "creep" factor that came from it being a game, but there is still a great charm to this game, and a lot of potential to freak other people out.
