I love the first track’s tranquility, also the chord switch at 51 seconds is really nice! The way the chords go back and forth almost feels like rowing a boat.
The fade-in of the other instruments in boss fight was really well done, but I really love the piano chords section around 1:33, and the fast arpeggios later on I also thought fit really well! And the wavering strings that join around two minutes in sound really nice. I love how you have the instruments interacting with each other in the song, it’s very creative!
