I tried to play deep sleep a few years ago at the age of nine, I couldn't do it. It was pretty scary for me then. Now It's still a little spooky, but at least I know these shadow creatures aren't going to jump out at me. On the second game finally.
Finised the game, it was awesome.
But, I didn't get the quests (yet I got 15 notes, got the key and made it through the whole game).
Still loved the game though
