It would fit perfectly a level that starts with heavy action and progresses to a platforming level. The start of the song fits very well in a combat situation, and when it breaks and starts building up again, it sounds very platforming like.
I would try to mess around with the panning of the two main melodic instruments, I think it could sound better if they were a little more separated.
Good track, and its great to hear some 8bit around here.
if you can, check my lastest track.. I would love a review (since it's 8bit too)
