This was fantastic and would carry any game that fit's your description. The sounds are all picked out very well, I love when that baseline before the loop doubles to change the sound a bit. Great use of pitch bending as well, and the arpeggio style of NES and GB is also just perfect. This is hard to master and even harder when the track is so densely packed with content. I also liked your use of panning, sometimes putting single notes from a line on the other channel to create movement. You could say I'm rather moved by this, no pun intended. Made me really happy.
