Someday I Will: You have a really interesting chord progression and a unique melody which makes this a really great and memorable main theme. The bass and percussion are well-produced and add energy to the track, which makes me imagine there is a lot of action and motion in your game.
Submerge In: The beginning has an ambience that sounds like a Donkey Kong Country game. The odd time signature keeps the listener on my toes and the fingered bass grooves making it seem like a normal time signature. The pads you use give the sense of being underwater which works well for that underwater sound.
Fight the Doubts Away: This is a great battle theme that flows very nicely from the rest of your tracks so far. I’m impressed with your breadth of vibes AND cohesiveness so far!
She Used to Play This: Your 7th chord syncopations give this a jazzy undertone, but it also feels waltzy, which works great for underwater vibes. Great way to tie the theme back in.
Today Is The Day: Very nice boss track! The organ pad chords keep the underwater vibe while the bubbly synth pulses add to that feel. The buildup in this track is very well done and it feels like the character is moving between phases of the fight. The ending is really sweet and gives a sense of finality to the tension.
And One Day I Did: I like the return of the main theme in a more calm and serene form which helps show your sweet ending. I think your choice to end on a minor chord was very intriguing and gives a bittersweet feeling in Lulu seeing her mother again, but knowing that she is still gone.
Overall: I agree with you that your music has been getting better and better with each jam! I really liked this soundtrack for its clear sense of style and cohesiveness and never once did it feel stale. This soundtrack scores very high on my personal 6th rating category of “game readiness”! You captured many different emotions with multiple different themes and grooves. Great work and thank you so much for sharing!
