Not great
First off, I'll just rate the game, not the subject matter. It wasn't all that great or addictive. Is was so-so, not front page material. If this game had any other subject, it probably would have got blammed. The ending was anti-climactic as well. It was fun for a little while though, and it was challenging enough that I didn't win on the first try.
Now, on the subject matter. I'm actually guilty of cutting myself, never to kill, just to distract the mind. Oddly enough, I gave this game a 3 because I almost got satisfaction from it. For those of you who think I do it because everyone else does, go ahead and think that. I couldn't care less.
