Hey Kai! Thanks a lot for giving the game a try and constructive feedback :)
Your meters feedback is super useful. Reading it I thought: damn, why we didn't think of it ourselves hahah! Guess it definitely has something to do with how focused you get on actually finishing the game for the jam so such little neat details escape your attention.
Also I like your audio cues idea, this will allow to keep players' attention on the stave while communicating to them that they are entering danger zone of losing the game and need to catch up with a stat. And the numbers on the dots make a lot of sense as well, will definitely make it easier to perform new melodies and I don't think it will trivialize the game challenge.
