I like it
I found this fun little piece while browsing for Earthbound music. I don't know if you know about the Mother game series, or if you even had it in mind as you composed this, but it reminds me of the battle themes Kraken of the Sea and Battle Against a Weak Enemy found in Mother 2, which was called Earthbound in the American release. I've always been a sucker for well-executed "crunchy" sounds, of which there are plenty here, along with fun pitch and rhythm variations, which are well put together to my ear. As a matter of taste, I think that a melody, or at least a tuneful progression of sorts, would make it a bit more interesting. This held my interest just fine without either of these, though. I'm off to check out some of your other work, and if you've never listened to Earthbound's music before, you may find some inspiration in its battle themes. Keep it up!
