This was a work of art. I don't know how you were able to do this in such a short amount of time, it's incredible what you were able achieve. The art and environments were so gorgeous. The parallax scrolling you had was huge in immersing me in this world. The character moves around so smoothly. You feel lightweight and breezy as it should, and wow it felt so good to control.
If there are any things that could benefit this game going further, I suggest illuminating the lanterns more when you're falling down the cavern. It felt like they just faded into an abyss and it didn't feel like they were really glowing. I also suggest having a sound to indicate you've touched the lanterns. It did take me a few seconds to realize what exactly were the lanterns, so any further visual indicator or audio one would help here. Overall this was spectacular, and you really seem like you could make more great games in the future.
