Great for a flash game loop!
Seems like a funny little diddy that I would hear at a piano bar back in the old west. This isn't a type of song that I would listen to in my spare time, but it is great for a game such as that one Cuboy game where he goes back in time and hangs out in the.. old west. I think you could have worked on the looping for this, as it would make a great loop.
It really does show proper knowledge of music composition, as you had a good selection of instruments with well done tunes and a good mix of leads and background to really keep the song going. You should try participating in this years game jams coming up, where teams of 5 get together and make a game / animation. You would be good for music.
For what this song is, it would be great for a flash game, but just not something I would find myself listening to in my spare time unless it was backed up with some sort of clever musical lyrics.
