That dist.zip you've just created, you need to upload them here so more people will get to notice & play your game and don't need to open GitHub repo to install it.
But anyway, I downloaded the dist.zip from your github repo and it worked on my machine. You really need to put it here on the itch.io game page.
You nailed the theme interpretation. The idea of variable jumping power according to the scale is fresh & great and this is my first time experiencing this concept!
