Amazing sound design on the second track! Keeping a reminder of the opening track in the melody which was the sailing theme and so, the main theme of your game while adding these sound effects transforms the experience of the player. It really gives shivers and implies madness coming, you can feel something's sneaking around you, and it's not good...
Strangely, I felt like there was too much reverb at the beginning, but I lost that impression in the middle of the album so... Who knows maybe it's me but I wanted to let you know.
Even if you used pre-made sounds, you did it well. Listening to the last track just confirms that you can create amazing atmospheres, I'm almost lacking words to describe that last one, and that feels very Lovecraft/ "eldritch"? (Google that as I didn't know the word). This one is terribly cool!
Overall, very innovative and cinematic soundtrack, such an ambiance you've created! Keep going :)
