I like the set design, and all three of the songs were nice! Are they original? I always like hearing / seeing assets that devs make themselves rather than pulling something from free assets online.
I also like how the notes to play line up with the sounds in the beats in an interesting pattern. The note timing seemed well aligned with the sound of the beat, but a bit out of sync with the visual target.
I was a bit confused when I saw several notes that were within the "held" notes, which I'm not sure how to handle... But other than that it was a very clean experience! Great work :)
