Not the best, yet not the worst either.

It's rather repetetive and not too complex. It is not something I'd like to listen to over and over, like some other of my favorite Techno/Video game songs, but it's nothing to laugh at either. Get different notes, I counted like... 5? Maybe more, maybe less. I wasn't paying too close of attention. Make the note changes faster and don't repeat things so often. Keep it up and you will improve.
