I'm searching for the name of a DS game. You could walk through corridors in an old castle. Everything in this castle tried to kill you. There were traps all around and you could collect keys. The game is in an ego perspective and, if I remember correctly, there was a girls name in the title and something with letter. But I#m very unsure on the name :S You also had a keychain with spikes that the main character would touch sometimes to calm down :S the main character wakes up in a room and sees a letter that is written for her... any idea ? :S
