Very nice
Very energetic. Makes me feel happy!
The melody is nice, and the bass sounds harmonic with it. You stated that it's quite repetitive. It is slightly repetitive, however, I've heard much worse; you actually did a pretty good job.
I do agree with Waterflame, however. Adding another melody would make things more interesting. Apart from that, the effects and drums are nice as well.
All in all... I think this deserves a 9 / 10 and a 4 / 5
Keep up the good work!
