A little bit repetitive, but you added a nice bridge to help. I love what you said below about all your old stuff that's on newgrounds, lol. I'm still publishing that stuff, in a way! XD
It's cool though; you've got a balanced piece here. The bass seemed a little overbearing, but I'm using my crappy headphones right now, so, yeah. I think the melody is addictive. Nice work with it! :D
