The game looks and sounds awesome. I really like the music and how it fits with the aesthetic.
The difficulty with the controls comes from it snapping into place which makes the blocks in between a little difficult to hit. I feel like something where you could have dragged the mouse would have worked better.
The music gets a little repetitive towards the end. A nice melody would have worked well to keep grabbing attention and maybe some audio feedback when getting a perfect would have been sweet.
Still, overall a fun rhythm game!
