Not great.
My first negative review of yours, I'm sad to say. You only used 1 real 8-bit instrument, and that one peaceful sounding melody + all of the hardcore drums is not a very good combination. The melody is great, though. The transaction was smooth, too.
I first clicked on this, looking for new songs on Newgrounds me and Open can remix, and then I saw the word 8-bit. I clicked on it, and listened for a little while, and decided to check out more of this guy's stuff.
Then I saw your name.
Well, you may want to make a new song, because this is good, but might not cut it for the RUNAGDM contest.
