Overall I like this project, although the "Cave Story" song does not sound like a particularly original remix. It sounds mostly like the dude just NES'd the orchestration and released it (with rhythm intact). If the other tracks weren't so much richer and more elaborate, I may have not have noticed.
Speaking of elaborate, I really really want to love "Never Die", but it's killing me that I can't sense the Final Battle's last melody. You can hear the main line from the rest of the Final Battle music, but it seems like the song never quite reaches the climax because that last melody never stands out. Even the part where the song tops out at is great (which is probably supposed to represent that melody), but it would seem nice to have another sequence where that melodic line is brought out more clearly. That's MNSHO anyway.
It's too late at this point, and it's just an opinion, but that's what I felt about it. It's just nagging me because it's so awesome.
I'm really looking forward to Oppression and Eyes of Flame remixes.
