One of those games which plays at being a puzzle but the only solution is to really bump your head against every surface until you find the necessary things to progress. Like, multiple fake walls just isn't the best design for this kind of thing, you know?

Still, I wasn't the biggest Yume Nikki fan and plenty of people loved that game, if you did there's a strong chance you'll like this one too. It's got a nice soundtrack, I'll say that much for it.
