Okay, so the game is decent. But i'd recommend using some background music or sfx sounds for moving/jumping/winning/losing or maybe taking damage?, Also, a quick addition is making the camera have a movement box inside it.
It's easily doable. In Godot, go to your camera 2D and select it, go to drag and enable horizontal and vertical drag. In the small menu below it, you can change the margins of the movement box. Thats always like a quick fix on making a game feel better for the player (i use it in my game aswell!!!)
But overall it is a decent game; I like the simplistic settings of it. And well, yes, I wasn't able to finish without taking damage
