Very solid game, especially for a first-time game jam. I like how the crowd grows as you successfully hit the notes properly, and you've got chances to get back into the rhythm of the game if you mess up. I do think it could be a bit of quality of life if the notes where changed to be bigger or maybe had an additional outline color to them, perhaps, but that may just be my own perspective on it. Beyond that, all I can really say is maybe the visuals could be fine-tuned a bit more, but after that, all I'd hope to see is just more of this game if you choose to do so. I wish you well in your game dev journey going forward
