I like the music very much. The classical music in the menus are great and the action music is awesome for 2005.
The graphics are fairly good and even better than I remember, and it beats the heck out of games now, but mostly those who ether post the first game they did or didn't try enough, but the text is leaving me wanting more.
The game itself has something odd I discovered: Fly to the top of the screen in any boss fight or. in some cases, into the boss.
It being unfinished, however, makes me wonder if you'll truly finish it if ever. Updating it with modern day graphics, cleaning off some edges that are noticed only when paying mass attention to it and maybe adding some new levels, mechanics, upgrades and having the BOSS ITSELF hit you, as well as limiting yourself to the screen or at least where you can see the bottom of your wings so you're not invincible.
But there's one problem. Non existent plot. Maybe have the plot littered through the game, maybe tie it in with the action, have the bosses speak or at least show text if you improve it.
Altogether, it's not my whole favorite, but it's still good and the great parts shine through. If you will, and people may agree, please finish and/or redo it.
