You really nailed the visual and audio aspect of the game, really love the doodly style, how the different strokes look, the best use of minimalism there is!
As previously mentioned, the notes you play are not always synced with the audio, and it's hard to figure out when you have to drag quickly / slowly, although when I got things wrong it didn't feel that much like a failure, so that did not impact the experience too much. A lot of emotion in this one, thank you for making it :)
