Very, very good
Firstly, sorry I'm so late in getting back to you.
Let me just say that this is a very well produced track! The melody and chords are excellent, I have no chance of producing something like that with my keyboard skills, I'm very impressed.
I'm not sure why you used the same instrument for both the main parts though. It works though, they're well balanced.
The bass suits the track well, good sound choice, but it kind of dissapears after 1 riff, oh, it comes back!
That solo over the top reminds me of slower versions of heaps of Nintendo game music I used to play all the time. Good slides and harmonization
Keep it up man, this is a fine effort :)
Just a thought, if you stuck in an acoustic guitar to replace the synth, you would have a very good foundation for some lounge music.
I can honestly say that, if I ever make an epic flash movie, this is the first candidate for the end-credits.
