Very nice in terms of overall presentation/consistency throughout the tracks. The soundtrack clearly has a vibe that it's going for and I think you nailed it. The Entropy boss theme was by far my favorite track, tho - it was really outstanding, great energy and production, feels really professionally done. My only real critique is that I think some of the tracks don't sound like they were mixed the same way. For example, "The Earth, Ten Billion Years Ago" sounds a little too lofi when compared to something like "Vs Entropy." The former sounds like it's from a 90s era 16-bit game whereas the latter sounds much more modern - this is especially apparent with regards to the high end in both tracks.
