Veeery nice. Chiptune and shoegaze in one song is a fantastic fusion I've never encountered before, and they're both some of my favourite genres.
This song is well done, though I think it could possibly be mixed a little finer. I just feel the volume levels for some of the instruments in the 2nd quater could be better balanced.
But otherwise, this song is immaculate, and I really dig it.
Keep it up.
