Thanks a lot for the feedback and glad you liked it!
For the theme, I went with the interpretation of playing a role that you wouldn't normally play. In this case you take the role of the sound effects instead of the main character in the RPG. It's different from a typical rhythm game because the events are generated by the actions of an AI character exploring the RPG world rather than scripted directly based on the music . I think if I had more time to add additional mechanics it would've sold the idea a little better. Definitely something to improve for next time.
