Thanks! The bubble glitch is something that we'll be working on fixing. I really appreciate your comment about the music! I had never made music before, and made it last minute. Since it's a repeating loop that only lasts like 10 seconds, I was worried it would get repetitive.
Edit: Bubble moving with player bug is mostly fixed when the player moves down, when the player moves up, the bubble accelerates a bit. I also improved the bubble's collisions
Edit 2: Bubble glitch is fully fixed
