Oooooh... The mystery... the ATMOSPHERE! Very well done and each song, while their own, continued to reveal the whole picture of the game, whilst staying true to the theme. You also had a very clever use of a leitmotif in hiding it, yet making it (even almost subconsciously) obvious! (which is very good!)
Lights Off was my personal favorite from your submissions, and I was thoroughly SPOOKED!
Great job and so far yours was one of my favorites that I listened to!
