Hey, thanks a lot for your comment! I looked up some of your work and I really appreciate your offer.
However, this project is a bit of a "me making an entire game by myself for fun and learning purposes" kind of thing, for better or worse. Actually, learning how to make music is part of the goal, even if the result isn't professional (that's also why all the tracks are going to be remixes).
I'd like to look into real chiptune music and trackers sometime, but probably not for this game.
