This game felt like a fever dream where I'm suddenly thrown into doing something I'm completely unprepared for lol. I love it.
The experience is really unique and the concept is great too. After a few play-throughs of the songs, I got into it and could figure out about 75% of the controls.
Overall, its both eye candy and ear candy to play. Adding in a correct or incorrect way to play could improve it drastically too. I think an end goal or purpose to mixing well would give me more incentive to try different things and improve at the in-game mixing.
