Production was really well done, best game I've played, ever. The story line appeals to my twisted sense of humor, how they made stuff look innocent and creepy at the same time is beyond me. I believe attraction to any game is roughly 60% about the music. The music is great, comes in at the right times, the sounds aren't obnoxious. The puzzles have me working my brain, really challenging, with level options. Really well thought out and executed. Loved it!
