the musical whiplash between the first two tracks is insane but i love it. overall this soundtrack is really, really funky. such a vibe! bustling brain felt like it was straight out of a persona soundtrack (which means it's extremely groovy). battle against a traumatic opponent was a really cool tone shift that i think works very well in this ost, as without the song this ost would lack diversity throughout it all. let go is also a really good song to use as a sendoff, love it's placement. a suggestion i have is to work on sound selection. there were a lot of parts in these songs where i felt a soundfont or midi you used kinda messed with the vibe. the songwriting is absolutely there, though. great job.
