Nice aesthetics! it took me a while to figure out how the points work and what you need to do, but it was nice experience! I think adding sounds to freezing crystals would make it feel extra cool :) Great submission! My main suggestion would be a bit more explicit feedback on players' actions - the fact that notes give you scores just arriving makes you question why you get a score without doing anything, and actually, freezing crystals might feel like delaying giving extra points.
