For the open source category, you'll need to have a README file and License file. Might be a good idea to structure your repo a little so you have things like "assets" and "src" folder rather than everything in the root repo.
I like the music and sound effects. Really random that my ball/sphere thingy just goes through stuff though. Maybe start with slightly smaller and easier level so the player can understand controls and physics, and then get harder. Wasn't immediately clear what needs to happen. I would also make "spacebar" the jump rather than "SHIFT" since shift isn't as intuitive.
Maybe check out the scaling too, since on my screen I had "Please bring me some" and the rest was cut off the screen. Good vibes game and nice work on your submission.
