This was a great concept, but I was able to jump on the boomerang, but not easily- the player is too "slippery" for this kind of platforming and the boomerang movement is too chaotic when thrown- but maybe it is just me that I am bad at platforms :-D. I would suggest to let the boomerang move predictably after thrown (e.g. like Mario Odyssey) for a better experience. I liked the mood and the aesthetics the most. Great job!
