I really liked the visuals, but unfortunately the game has no spam protection, as soon as I realized this, it became much more boring to play because I can just click on all the levels.
It would also be nice to see the record displayed somewhere in the menu or when hovering over a song, since now motivation is lost because you can't see your best record.
I would also like to have a little more mechanics, for example, so that to activate fireworks you need to hover the mouse over the circles and click on them. Since now the gameplay is very simple and quickly gets boring.
