This album def works well together. Very chill vgm music, executed well and i love the little creative production techniques used that add some spice and life to the tracks. Motifs/Themes/Leitmotifs (whatever you wanna call them) are def noticeable.
I try to give some constructive criticism for every compliment i give but since I'm no expert on this kind of music, I'll just say I wish the boss battle had some more energy! Having that high hat playing at faster rhythm or at least a BPM increase would be sweet. Lacking low end as well, but hey! creative choice, who am I to say whats right or wrong!
Cheers!
