Great mood and soundtrack/sound effects.
I thought the camera was against me though. It was really hard to react to the level in a the speed the game reaches. I was just blindly jumping every time I saw different colored stuff. Maybe the camera could be bigger (show more stuff) or, at least, adjust it so the player sticks to the far left of the screen. As the levels makes you go right, that's what I'm interest to see in advance to make a plan and act. The visibility doesn't help either, as the background is very noisy and calls for your eye's attention (specially the blinking lights)
Another improvement I would think about is the visibility of the tape. The leve makes your eye look to the right of the screen, but the tape is on the upper left corner, so you have to move your eyes a long distance everytime you want to check on the tape color/buff. One simple solution would be to just change it to the upper right corner, this would already help a lot.
Hope these feedbacks help! o/ Congratulations on the project, very atmospheric and polished as well.
On a side note, my game is also music themed haha a rhythm game actually
