If you're creating music for Flash Games, I better move your thread to the Programmers Forum. If you're simply looking for general feedback, then this Forum is best suited!
From what I have heard the songs are a bit mellow in pace, I could see some would make excellent accompaniment with cinematic in games. Though I would like to ask do you have any short loops to show? I mean some of the music in games are just 30 second loops or less sometimes to keep file size down.
I would also like to say that one of my favorite games that the music really shines is Castle Crashers it also has a fairly varied mix of music and I think if you play games that songs can really drive the memory of levels and gameplay.
