Wow congrats on writing 32 minutes of soundtrack! The themes are all really catchy and capture that rhythm game feel. The visualizer is really mesmerizing.
I think my only complaint with this is that sometimes the music felt a little loopy and repetitive which isn't something you always want for a rhythm game since the player would just be making similar movements repeatedly. For rhythm games you want the player to always be on their toes and adapting to dynamic and rhythmic changes and shifts.
Great job with this though, your descriptions were detailed and really helped tie the story and the music together, this is really cool!
