Such a creative bullet hell idea. Idk how many bullet hell/platformers I've seen, we need more! I love the design of how you have to go towards the rewards above the notes that shoot bullets, it was an interesting push and pull. I do wish there were platformer polish bits like coyote time (being able to jump a bit after you fall) and jump buffering (if you press jump a short time before hitting a platform you still jump) but those are only a bit of polish. I was also confused when I started as to what each upgrade did, so it would have been nice to have a pause menu where you could read the instructions instead of only being able to read right at the start. Overall I had a hard time coming up with critical feedback so this was a really polished game, great job!
