If you know the tale then you're safe but if it's unknown to you, I recommend getting your heart ready for a fright.
This is one of those games that requires nothing much to be amazing, it just is amazing without special effect or astonishing soundtracks or spectacular game-play because if it draws you in it really is a fright. At first i didn't think much of it i knew the tale and what it was all about yet it still gave me a fright and made my heart race.
All in all it was amazing, simply amazing, well built, nicely done and astonishingly simple.
