I had a good time playing this one, it's pretty addicting when you get the hang of it. I like the music chart at the bottom showing when the player's attacks run, as well as the variety of timings for the different weapons. It was also quite neat how the song slowly builds up over the course of a run, with each instrument slowly getting more intense to help sell the feeling of getting stronger. I also though it was neat how the song worked regardless of the instruments picked up while managing to stay distinct between builds.
The game would probably benefit from more sound design alongside the music. I had a hard time noticing when I was taking damage in the middle of fights without particle or sound effects since I wasn't paying much attention to the edges of my screen. Levels were also a bit too large especially in the early game before you have a chance to upgrade your speed.
Very enjoyable, I found myself wishing it went on longer once I reached the end,
