The association of this heavy rythmic section add janky sounding banjo(?) is certainly a great fit for the earthbound game. I am not as confident for the note choices, some of the dissonances are hard to swallow for me, also the bass being so deep sometime I can't really grasp what is going on. Adding a B section somewhere could help break the repetitivity and create a good opportunity to have a comeback of the A with an additional instrument, maybe even switch the banjo(?) for an other lead the second time.
