This is the perfect song I was looking for for my flash game. I will be using this, but it's for a class so I won't be publishing it. I will add credit for you anyways.
And to answer your question, I believe that this is the right genre. Also I believe you should add that it's a loop more than a song.
I'm not rating this out of 10 because I don't believe that this is the best song out there, and I apologize for not telling you what the problem is, it's just... I guess it's because it's your first submission and I would like to hear some others to compare. But good job on your first song/loop anyways. :)
Sorry for my Engrish, it's late and I can't think straight at all.
