This is super cool like others say, but I will put my comments on some tracks so I don't just drop a "nice" and move on.
Crystal Zone, I feel like it needs more syncopation. Specifically the section 0:50 to around 1:30 feels like it wants to be this breakcore drum thing but its seems to hit the fill on the and of 4 every time, which makes it feel really predictable when the song kinda gives a vibe of not the 4/4 yeah? I think it would sound interesting going the e and of 2, then and uh of 3, etc.
Lava Center Zone, I think the instrument used at 2:20 and other parts of the song could be a little brighter? It sounds choked to me, especially since it takes a lead in multiple parts. Maybe the high end eq is too aggressive for my taste?
Time Bomb Zone, that sweeping drill noise doesn't lead to a whole lot of replayability, it might get tiring quickly ingame. Maybe some other sound design choices on it would the mitigate the "problem" for me, not sure thought. It is definitely used a lot in that song!
Great work man, mad respect for 18 minutes of music.
