Really cool! The production is awesome : it hits hard, it's very well mixed, and it just sounds really good.
The Level and Boss themes groove hard, and the Title theme less grooves and more... vibes. It help energize the track without ruining the atmosphere.
I really like the hook you got here, and that you reuse it for the boss theme (with fitting changes ofc), but i wish you developed on it more : maybe in the level theme, you let the hook play twice, then develop on it, continue the melody, and then come back to it. It would make the track have a really nice structure without having to change harmony or beat or anything else. With the boss track i'm actually pretty ok with the hook staying undeveloped, because it helps adds to the tensity of the track.
Overall, i liked this a lot, and i enjoyed grooving out very much.
