I really liked the puzzle style and the atmosphere of the game. I also liked the core ideas in the story. That said, the story feels like it isn't fully fleshed out, as if perhaps the writers decided they didn't have time to really establish all of the ideas, so they just cut some out. The result is a basically good story which feels less than fully supported. Its far from being enough to ruin the game, though, and I would absolutely play through more of the same if the developers ever released an expansion or sequel.
