The puzzles are only difficult at first because they're not puzzles, they're pixel hunts for answer keys. There's no thinking involved, you just have to click around randomly until you find the button that makes the note pop out. Between the godawful color schemes (which are too dark and have way too-low contrast for anything demanding pixel hunts; several of the buttons and items blend in so well with the backgrounds it's impossible to tell they're clickable) and the complete lack of direction, the only difficulty is the pixel hunt, and once you get used to the pixel-hunt logic and learn to tell the difference between "inventory item" and "background fodder", there's no gameplay anymore. There's no story and no point, just another boring, cliche, maybe-it's-sci-fi-but-since-there's-no-context-it-doesn't-matter setting with a creepy, tense atmosphere that never actually builds up to anything. That being said, the graphics are pretty good, color choices notwithstanding, and the music definitely supports the unsettling ambiance very well.
