Track 1: I love the piano-cello combo! Definitely a very beautiful track. It would have been nice if the chords changed at some point, but timbrally it was on point.
Track 2: as someone who loves reorchestrating stuff to be chiptune, this is a really cool rewrite of track 1!
Track 3: always a good idea to use fragments of existing material in cool ways, and I like how you used the main theme in your game over!
Both main tracks were cool, but I'd love to hear them more fleshed out with more musical content. Still, both are really great!
