Really enjoyed the first track, and the crackling sound-- reminds me ever so slightly of Everywhere at the End of Time. Definitely a cool groove and a good opening, with some nice attention to detail as well.
Track 2: Love the quartal harmony! This track does a good job of establishing the mystical, dreamy feel of the game. Beautiful flowy synths, cool chords... would be a good song to study to, I think! The constant addition of cool new chords really keeps this track sounding interesting.
Track 3: Lovely tone shift! Definitely a more upbeat track with a cute little melody.
Tracks 4 and 5 are both quality, but I really love track 5-- this is one of the most suspenseful tracks I've heard yet in this whole jam. Really amazing job, and it gets you hyped up for the fight track!
Track 6: quintessential hip-hop fight music. Love it! Really good job of creating a high-energy track.
Track 7: Mario Galaxy vibes!
You did an excellent job of telling a compelling story and creating a unique, beautiful world (right down to the awesome coverart.) this was a great soundtrack, keep writing!
