Here are some of my thoughts on each of your tracks:
Valiant and Volant!- Very upbeat, it has that energy of setting out into an adventure
Hovering and Homesick- Cool dreamy vibes.
All Aboard the Airship- You really captured the level selection menu with this one, It makes me want to select something right away!
High Spirits, Higher altitudes!- High octane battle theme in the sky, very cool!
Mile-High Magma- Holy s**t! the melodies in this one are really catchy!
Death by Drigible- This has that "if you don't hurry you will die" feeling , I would feel very anxious playing this part of the game so good job? xD
Dream-Dyed Aerodyne- This one has a very dramatic atmosphere and also a magical and ethereal aura proper for a magical Boss.
Mission Clear! - Oh yeah, Party Time!
I loved your entire soundtrack, and the way you described everything made it so much real to me, very well done!
