As I have already written in your feedback form, the game does not feel rhytmic at all. I think that disc up/down movement should always match the song, as for now music does not enhance the experience, but even makes playing harder.
And about tutorial: I got hang of the movement after about 1 or 2 tries. Tutorial helped a little, but anyways 1st level all seems to be a big tutorial (little too long).
I appreciate that there is always a safe enviro first, like with those skulls. In the beginning you don't have to worry about 'em and after few seconds of introduction, you have to use this new knowledge. It's not that you have to die to learn a new thing here.
Oh, and I love those jelly aesthetics.
