The game is getting really good.
Map
It is very beautiful, but it is a bit confusing of what is the stage, it would be nice to have a name appearing when the player is on the stage ball.
Gameplay
I think the character is heavier than it should, improve the acceleration of the fall a little, making it fall a little slower, maybe increasing the height of the jump a little.
The camera has a small problem, as it seems to update abruptly, to solve this problem, put a lerp in the camera movement to make it smoother.
During the gameplay, I was not able to understand well what is the criterion for the character to die, if it is due to being hit 1 time or several times, because I took several blows the first time I played, when I restarted the stage with 1 touch on the enemy I already I died, got a little confused.
End game
I saw only 2 levels, it would be good to finish the demo in some way, leaving the link for the game to receive support, maybe even a new phase with only one screen and clickable links.
The game is very interesting in general, congratulations on the work.
