I didn't find this to be one of your best. I guess I just thought it was too short. At least you claim it's something that was new for you at the time. I don't specifically remember this music. Then again, I might not have played the original Donkey Kong. I can definitely recognize your voice.
We've all done stuff like this before. It just isn't that original. It does work well as a loop. It's hard to tell when it stops or begins. You always make good stuff.
