Hey was able reach the magic boots part, the main issue to me seems to be the lack of coyote-time it would probably make the player 100% better to control(I think theres nothing wrong with the jump), the art style is unique and reminds me of mosaic paintings lol, and I have never seen an health bar done that way.

Just played it and was able to get much further this time, until the first snake type enemy, for your future project I would advice trying to help out as much as you can the players that are failing, for example in this game the health bar could be restores when you respawn making it easier but only for those who are struggling/dying.
