Very great soundtrack, with a lot of though and work put into it !
I really liked the intensity of the instruments and arrangements you've used throughout, it really did a lot for the theming of your game. Among the tracks, Overcharge was really nice with its many variations and high-adrenaline energy, and At Last provided a nice breathing room after all of the intensity of the previous track.
I quite liked the thought you put into your worldbuilding on your page and it's really well done, however I must say that reading through your descriptions and listening to your music at the same time was almost impossible, due to how busy and intense the tracks were and how compact and blocky the descriptions were.
This is not a problem at all since I read back the description after finishing your album, but maybe some shorter sentences and a lot more line breaks could help with the readability of your synopsis (because I felt that it has a lot to offer with the illustrations that are also very nice, you can compliment your friend for them) ?
Anyway very great experience, I enjoyed a lot being immerged into your worldbuilding along with the great music/story/illustrations to represent them, so well done !
