Well thought out and with a lot of interesting ideas scattered throughout. The thought and care put into the write-up alone had me certain that the music would be the same, and I was not wrong!
Some really nice arrangements in here and with some choice instrumentation. I liked how consistent and congruent everything is - each track fits in the album as a whole but works independently also. I think my favorite of the bunch is Octo-Popper Supreme - Final Boss Theme - the brass work in this is great.
Production is great all around and I think there's a lot to be said for how thoughtfully orchestrated all of this is. Major kudos for the video as well - above and beyond in terms of presentation. Great work, best of luck! :)
